Laser (laser) is the abbreviation of "light amplification by stimulated emission of radiation" in English, and is also called laser in Taiwan. It is another major invention of mankind in the 20th century after atomic energy, computers, and semiconductors. It is called the "fastest knife", "the most accurate ruler", "the brightest light" and "singular laser." According to experts, lasers are extremely versatile. There are laser lights for stage decoration, laser projectors for classroom presentations, laser pointers for instructions, laser scalpels for removing eye bags and correcting myopia, and they are frequently used in life or work. Laser recordings, laser printing and laser phototypesetting, new laser projection TVs used in the Beijing Olympics, etc., lasers have long been inseparable from our lives.

We must pay attention to the safe use of laser

In order to reduce and prevent this kind of high power laser pointer damage, my country has formulated several standards for laser safety, such as the "Radiation Safety, Equipment Classification, Requirements and User Guide for Laser Products" issued by the National Bureau of Standards in 1987, and the National Bureau of Technical Supervision in 1988. The "Electrical Safety of Laser Equipment and Implementation" promulgated in 1989, the "Laser Radiation Hygienic Standard for Workplaces" promulgated by the Ministry of Health in 1989 and the "Laboratory Laser Safety Rules" promulgated by the Ministry of Machinery and Electronics in 1991.

For laser CD players and printers used in homes or offices, due to the specially designed structure, the blue laser pointerpath is sealed in the machine, which can generally ensure safety, but it is not ruled out that some products will radiate part of the invisible infrared light. The more invisible, the more dangerous. For visible lasers, most people know how to protect them, and at least they can’t look directly at them, but for invisible lasers, most people have no experience in this area. People should pay more attention to the safety protection of laser light path products outside the machine.

These are one of the latest 20000mW color high power laser pointer with a wavelength of 405 nm, only in the visible spectrum. Therefore, these lasers do not look so bright, making users feel that they are not as threatening to their eyes. The classification of laser pointers purchased at dangerous distances is based on the risk of injury. Since the laser output is usually a narrow beam, the beam may exist for a long distance. An important parameter in laser risk assessment and management is the Nominal Eye Hazard Distance (NOHD). This is the distance from the laser opening when the laser beam directly hits the eye and will exceed the maximum allowable exposure (MPE) level. Except for NOHD, exposure to laser beams is generally considered not to cause any harm to normal people.

Correct laser maintenance can extend the life of the laser. We only need to follow the steps below, what do we need to prepare?

1. Microfiber cloth Please make sure that the microfiber cloth is specially designed for lens cleaning. You can buy it at a local camera or glasses store. 2. Cotton swabs or toothpicks You need to use a cotton swab or a fiber cloth folded in front of your eyes to clean the blue laser pointer lens. 3. Lens cleaning kit (optional) If you cannot clean the lens thoroughly with a microfiber cloth, you need to use a lens cleaning kit. Make sure that the cleaning kit is specifically designed for lens cleaning.

Class of laser pointer

Class I: Low output Green laser pointer (power less than 0.4mw). There is basically no harm to the eyes, and the safety of the design can be guaranteed without special management.

Class IⅡ: Low-output visible laser (power 0.4mW-1mW), usually less than 1mw laser, can cause dizziness and unable to think, use closed eyes to protect, generally can eliminate the symptoms. Do not observe directly in the beam, and do not directly irradiate the eyes of others with a laser less than 1mw, and avoid observing ClassIⅡ lasers with distant vision equipment.

Class IⅢ has IⅢA and IⅢB:

ClassIⅢA is a continuous laser with visible light, and the output is 1-5mW laser beam. Avoid using distant vision equipment to observe the I laser, which may increase the risk. Like ClassIⅡ, do not observe directly in the beam, and do not use ClassⅢA laser directly. Shine the eyes of others.

Class IⅢB continuous laser is 5-500mw, it is dangerous to observe directly in the beam, and do not use Class ⅢB laser to directly irradiate the eyes of others, which will be even more dangerous.

Class IV is a high output continuous high power laser pointer (greater than 500mw), higher than the third level, there is a danger of fire, diffuse reflection is also dangerous, especially worthy of attention. Children, please avoid watching this type of laser directly.

Summary: Class II, Class I III A, Class I III B, and Class IV products have certain hazards. Please use them under guidance and supervision. Children should pay more attention to them. Please use them under the supervision of parents or other guardians.

Small portable high power laser pointer are used to guide lightning strikes and prevent forest fires caused by lightning strikes-a study that could lead to such measures was recently announced.

Does the laser pointer emit radiation?

Basically electrical components have radiation. I have a friend who makes this product. The radiation of the Green laser pointer is very small, and there is no harm to the human body. But don't irradiate the eyes to affect vision. Improper use of laser can cause temporary or even permanent visual damage. Looking directly at a laser with a power of 5mW and above will cause temporary visual damage to the eyesight, and a higher power will cause permanent visual damage or even blindness. High-power lasers may ignite flammable materials and cause fires.

Can portable laser products be sold?

Battery-powered portable laser systems can be sold in the United States, provided they are fully compliant with standards, certified and reported, and are not Class IIIb lasers for pointing or entertainment purposes. Personnel operating Class IIIb portable laser systems should be familiar with the above ANSI standards for safe use of lasers. The ANSI series of standards include specific information on the safe use of such laser products in their applications. IEC-International Electrotechnical Commission Standard 60825-1, Ed. 1.2: 2001-08, ANSIZ136 standard can be obtained from the American Laser Institute (www.laserinstitute.org).

The Green laser pointer is mainly used as a light pen. The history of these light indicators began with traditional lamps whose beams were strongly bound by concave mirrors or corresponding lens arrangements. The core problem with the first-generation pointing devices was that they were very weak. They are very suitable for lectures in dark rooms, but are not convincing during the day.

The budding period of the laser pointer

The idea of ​​blue laser pointer sprouted in the mind of one of the greatest scientists of all time, Albert Einstein, who tended to study light and its properties. He can understand the scattering of light (when light travels from one medium to another, it is divided into its constituent wavelengths) and properly study its characteristics. After observing the sun's rays, he had the idea of ​​lasers. However, he could not put it into practice. Nevertheless, he passed on his knowledge-in the realm of light characteristics-to future generations.

The actual beginning of the laser pointer

At first, the experiment was carried out in a series of invisible spectral ranges: microwaves (wavelengths between 30 cm and 1 mm) seemed easier to control at first. In the early 1950s, the physicist Charles Townes (* 1915) built a device-he confirmed Einstein's prediction-that could be used to generate and amplify microwaves, and named it Maser (the M of microwave) ).

The desire to do the same exercise with visible light (wavelengths in the nanometer range) led Towns and his brother-in-law Arthur Shalow (at the famous Bell Labs) to make efforts in the United States and the Soviet Union. Two physicists Alexander Prokhorov and Nikolai Basov conducted research. In 1958, Townes and Schalow were able to mathematically prove that what their masers can do must also be applicable to visible light. However, in their experiments, they used gas as the carrier medium, which did not work properly.

Introduction to laser cutting machine

Laser cutting machine technology uses the energy released when a laser engraver beam hits a sheet metal surface. The sheet metal is melted and the slag is blown away by the gas. Because the laser power is so concentrated, only a small amount of heat is transferred to other parts of the sheet metal, causing little or no deformation. Blanks of complex shapes can be cut with great precision using lasers, and no further processing is required after the cut blanks. The laser source usually uses a carbon dioxide laser beam with a working power of 500 to 5000 watts. Because of the lens and reflector, the laser beam is concentrated in a small area, so the power level is lower than that required by many electric home heaters. The high concentration of energy allows rapid local heating to melt sheet metal.

Laser cutting machine features

1. High efficiency. General laser cutting machine is equipped with a number of CNC worktables, the whole cutting process can be all CNC. In the process of operation, just change the NUMERICAL control program, can be suitable for cutting different shapes of parts, can be used for two-dimensional cutting and three-dimensional cutting.

2. Laser cutting speed is fast The power of 1200W Green laser pointer can cut 2mm thick low carbon steel plate, cutting speed up to 600cm/min; For 5mm thick polypropylene resin plate, cutting speed up to 1200cm/min. Laser cutting materials do not need to clamp fixed.

3. laser cutting quality is good Laser cutting incision is narrow, both sides of the incision are parallel to the surface, the dimensional accuracy of the cut parts can reach ±0.05mm. The cutting surface is smooth and beautiful, and the surface roughness is only dozens of microns. Even laser cutting can be used as the last step without machining, and parts can be used directly. The cutting precision is high, the geometric shape of the cutting joint is good, and the cross section shape of the cutting joint is a relatively regular rectangle. Comparison of laser cutting, oxy-acetylene cutting and plasma cutting methods is shown in Table 1. The cutting material is low carbon steel plate 6.2mm thick.

Development of laser cutting technology

Laser pointer, also known as laser pointer, is a pen-shaped transmitter designed to be portable, easy to hold, and processed into a laser module with visible laser. It is usually used by people in conferences, teaching, and tour guides to project a light spot or a light directed at an object. Laser pointers are often used as an eye-catching point in education and business presentations and visual demonstrations. The red laser pointer can be used in almost any indoor or low-light situation, pointing out that manual details may cause inconvenience, such as construction work or interior decoration.

Features of laser pointer

1. The high power laser pointer has more than one beam color, it has red, green, blue, orange, etc. Among them, the spectrum of the human eye in the green region is the most sensitive, which seems to be brighter than other colors, and is sensitive to red or blue wavelengths. decline. 2. Red and orange are the simplest lasers; yellow laser pointers are extremely rare in the market, unstable and low in efficiency. The output power is 1-10mW with temperature changes, and mode jumps will occur if overheated or overcooled. 3. Green light is a solid-state laser. Some green lasers work in pulse or quasi-continuous mode to reduce cooling problems and extend battery life. 4. Blue laser pointers usually have the same infrastructure as a green laser. Blue lasers can also directly produce indium gallium nitride semiconductors to produce blue light without frequency doubling; blue-violet light can be constructed with gallium nitride semiconductor lasers to emit at 405nm Purple light beam.

Laser pointer can be used in industry. For example, construction companies may use high-quality laser pointers to improve the accuracy of displaying specific distances while working on large projects. It can also be used in scientific research fields, such as photonics, chemistry, physics, etc.

When laser technology is used as an information carrier, military applications mainly include laser ranging, laser guidance, laser communication, laser fuze, laser radar, and laser shooting simulation training. These applications require little energy, and solid-state or semiconductor lasers are commonly used. When laser technology is used as a directed energy weapon, it has a great advantage over traditional weapons. After the 1970s, the United States and the Soviet Union achieved many successful results in the development and testing of laser weapons. This time we will briefly introduce the development status of laser weapons.

📷

According to the power of blue laser pointer weapons and the different combat missions, laser weapons can be divided into two categories: strategic laser weapons and tactical laser weapons. The energy of strategic laser weapons can reach several megawatts, and they are mainly used in ballistic missile defense systems and space warfare applications. The medium-sized powers of the United States and Russia have conducted experimental research on laser weapon anti-missile or anti-satellite weapons, and even have conducted research on anti-hypersonic weapons. The energy of tactical laser weapons is generally tens to hundreds of kilowatts and has a wide range of uses.

Laser history timeline:

Albert Einstein proposed laser technology in the early 19th century. This technology progressed in the 1960s, when the first laser was introduced in the Hughes Research Laboratory. Follow the timetable below to explore the evolution of laser technology.

1917 Albert Einstein predicted the phenomenon of "stimulated emission" (which is the basic principle of all laser operation), laying the cornerstone of laser technology. 1939 Valentin Fabrikant established the theory of using stimulated emission to amplify radiation. 1950 Charles Towns and Nikolai Sov and Alexander Prokhorov developed the quantum theory of stimulated emission and proved the stimulated emission of microwaves. With this pioneering work, the above three scientists successfully won the Nobel Prize in Physics. 1959 Columbia University graduate student Gordon Gould proposed the use of stimulated emission to amplify light. He described an optical resonator that can form a narrow beam of coherent light, and called it LASER, which means "Light Amplification by Stimulated Emission of Radiation". 1960 Theodore Mayman built the first working laser prototype at the Hughes Research Laboratory in Malibu, California. This laser uses synthetic ruby ​​as the activation medium and emits a deep red beam with a wavelength of 694.3 nm. The first application of this ruby ​​laser is a military rangefinder. Due to its high peak power, it is currently being used commercially in diamond drilling. 1963 Kumar Patel developed a carbon dioxide (CO2) laser at AT&T Bell Laboratories. Compared with the ruby ​​laser, the cost of the CO2 laser is greatly reduced, and the efficiency is greatly improved. It is precisely because of these favorable factors that this laser has become the most popular industrial laser for more than 50 years.

Definition of laser pointer:

A Green laser pointer is a small handheld device similar to a pen. It uses a power source (usually a battery) and a diode laser to produce a coherent monochromatic beam. The laser pointer is mainly used to highlight points of interest by using a strongly colored beam. The typical low-end laser pointer that comes with the key chain is nothing more than a sturdy LED used to ensure safety.

Laser pointer use:

The Laser pointer consists of a diode-pumped solid-state laser that doubles the infrared pump frequency. The diode usually produces red, green, blue and violet light beams with higher visible light power, usually up to 300 mW. The original laser pointer has certain safety hazards, because if it is pointed at the skin or eyes, it may be very dangerous and cause serious damage, so please use it carefully. A laser pointer was introduced to use low-power laser tools in daily use.

Laser pointers are most commonly used in business or educational presentations to highlight or point out certain things. Higher power laser pointers are also used in astronomy to point out celestial bodies. Laser pointers can also be used in many other ways, such as weapons for aiming accuracy and spirit levels for construction.

Laser pointer and stylus are important stationery in education and work. The laser pointer helps the teacher or narrator explain the PPT. Signature brushes are easy to write. Status or existing patented technology, laser pen and pen signing are separated, or the laser beam signing can have color, but in practice, for example, in addition to the laser indicator, you may need a signature black, red, change the training plan and hidden marking elements in class. Therefore, in addition to the laser pen, you must wear red and black with your signature. In addition, if you do not have signature ink, the signature will not work. Both cases bring some inconvenience to teaching and office work.

Start with a simple red laser, then collect parts and turn on lasers of different colors with terrible sound effects! In recent years, a red solid-state laser pump (DPSS) button has been developed on a diode with a wavelength of 671 nm. Although this wavelength can be obtained from cheap diodes, DSS technology can produce better quality lasers in a narrower frequency range.

The special feature of the new laser pointer

The laser pointer is now an important part of the teaching process for teachers. Teachers can use the laser pointer to indicate the location of the content they are telling. Modern teaching often uses PPT, and the teacher will prepare the PPT in advance and then put it in the classroom. Demonstration, because there are often more points on a page of PPT, in order to facilitate the teacher to tell the students the location of the points when demonstrating the PPT, the teacher will use a laser pointer when giving a lecture. However, the existing laser pointers are relatively similar in structure. They are all long strips, have no novelty, are inconvenient to carry, and are easy to lose. Laser pointer mobile phones have now become people’s essential portable electronic items. In order to meet more and more people’s work and life needs, laser pointer mobile phones continue to add a variety of practical functions, so all kinds of practical gadgets and small products are also It is continuously integrated into laser pointer phones, such as electronic watches, game consoles, music players, cameras, calculators, etc. Therefore, it is a development trend that laser pointer phones continue to integrate various small electronic products. The laser pointer involved in the utility model, also called a laser pointer or a laser pointer, is currently widely used in society for classroom teaching, shooting training, and field indication of targets.

📷

SUMMARY OF THE INVENTION In order to provide ordinary mobile phone users with a simple and reliable laser pointer tool, which is convenient for the user to indicate the target when talking with others, or to illuminate under special conditions, the present invention provides a laser pointer mobile phone with a laser pointer. The feature is that a laser pointer is installed on an ordinary laser pointer mobile phone. The laser pointer includes a laser diode, a transformer unit, a light-emitting power adjustment unit, and a control device; the light-emitting power of the laser diode is less than 5mw, and the laser wavelength is less than 800nm, The effective irradiation distance can reach 200M. With the development of science and technology, the traditional teaching and meeting methods have undergone great changes. Multimedia has penetrated into classrooms, meeting rooms, training rooms and other occasions in universities, middle schools and primary schools. In order to increase the interactivity and effectiveness of classrooms and meetings, and to attract the attention of the audience, the lecturer often needs to discuss and communicate with the audience. This requires a simple handheld device with wireless remote control that can continuously meet the needs of the lecturer. Change the content of slides (such as PPT, etc.), turn pages and other functions. At present, the existing wireless laser pointer can only realize simple functions such as laser point indication and page up and down, continuous page turning, but the actual situation is that the explainer often needs to change and emphasize the important part of the demo film during the interaction with the audience. Content, both need a simple handheld laser pointer device that can perform multiple operation functions in real time.

Medical laser is an important high-tech medical technology in this century. Laser medicine involves all clinical disciplines, such as ophthalmology, dermatology, surgery, dentistry, tumors, etc. Laser has a revolutionary breakthrough in medical treatment. Lasers of different wavelengths are suitable for different treatment fields. As an important field of laser applications, laser medicine has developed very rapidly and gradually matures. Semiconductor lasers are particularly suitable for the manufacture of medical equipment due to their small size, light weight, long life, low power consumption, and wide wavelength coverage. It is estimated that in 2010, 5 million laser hair removal operations were performed worldwide. Another important application of semiconductor laser in the field of cosmetology is skin reconstruction surgery, which is used for wrinkle removal and skin rejuvenation. The laser light is absorbed by the moisture in the dermal collagen tissue to produce a thermal effect, which stimulates the regeneration and remodeling of collagen, so that the skin becomes smooth and tender and restores its elasticity. In addition, laser can also be used to treat freckles, traumatic pigmentation, remove tattoos, eyebrow tattoos, eyeliner and other black and blue pigment lesions.

📷

With the development and maturity of semiconductor laser technology, its unique advantages continue to increase, and its application in the medical field is also expanding, almost covering the application range of other lasers. It not only makes up for the shortcomings of high-energy CO lasers that are difficult to transmit via optical fibers and is inconvenient to operate, but also makes up for the low efficiency and troublesome heat dissipation of lamp-pumped solid-state lasers, and is expected to become the mainstream of medical lasers.

Various types of laser beauty 📷

There are many types of laser beauty, and I have divided them into several types: Cutting: using the high-energy, hemostasis, and directional characteristics of laser, used as a scalpel, and cauterizing (removing moles, removing warts, removing hair, eliminating acne, etc.) , Grinding (scar repair, etc.), often used in plastic surgery. Digestion: specific substances are sensitive to the wavelength of the substance, then this feature can be used to dissolve these substances. For example, color spots, lasers of specific wavelengths cause less damage to normal cells, and can penetrate into the skin, bombard the spots or target cells, to eliminate and kill. It is often used for pigmentation and medical cosmetology. Excitation type: certain specific wavelength laser can stimulate collagen growth and cell proliferation. But strictly speaking, this does not belong to laser, but belongs to pan irradiation. Color light and photorejuvenation belong to this category. But beauty salons may also be confused when they publicize, and they often say that this is a laser (because lasers are relatively high-tech).

The first Laser pointer is a laser pointer with a single function. This pen has a laser properties and after a while, it was divided into red and green inexpensive red laser Pointers have become mainstream for everyday use. Green laser guns are expensive. Mainly used in construction and astronomical observation. It has the function of usb flash drive and USB flash drive. This pen can be used to write, connect to a USB drive, or use on a guide. This rule will be used primarily as an indicator.

The second generation of laser Pointers creates remote desktop manipulation of results based on ordinary laser paper data centers. The remote laser pointer accepts infrared technology to transmit remote control. His principle is TV remote control and DVD remote control. Daily air conditioning control remote control headquarters product is conformation space V606 remote control laser (conformation machine). Infrared devices also look older, more mature and less complex, and infrared products are relatively cheap. Using infrared technology to send Green laser pointer into libraries is very cheap and usually wins fewer than 100 people. Infrared cannot penetrate objects, so it must be transmitted visually. There must be no obstacles between the emitter, and the power supply of the receiver and emitter must be set at a specific Angle to facilitate the steering of both sides.
