#30000mw laser pointer

September 7, 2016, hosted by OFweek Chinese high-tech industry portals, network host OFweek laser, the laser industry in Hubei Province Association of the "OFweek 2016 China advanced laser technology and application seminar" was held in the Sheraton Grand Hotel Shenzhen · China. Zhang Rui, general manager of the new Shanghai Hanyu Optical Fiber Communication Technology Co., Ltd. in this meeting published the "ultra low noise single-frequency narrow linewidth fiber 30000mw laser pointertechnology and application," keynote speech, focusing on the commercial single-frequency fiber laser key technology and products to interpret .

According to Zhang Rui new introduction: "At present, in the commercial area of single-frequency fiber laser technology is mainly divided into the following four categories: 1 short straight single-frequency DFB fiber laser cavity; 2 straight short cavity DBR type; 3 complex chamber technology; 4 and the annular chamber composite technology annular cavity.

Four technologies have advantages and disadvantages, such as the advantages of short straight single-frequency DFB fiber laser cavity is a simple resonator structure, FSR up to GHz, easy to implement single-longitudinal-mode output. The disadvantage is that the 1/4 wavelength phase-shift fiber grating requires high technical difficulty, the doped fiber doping concentration between the noise and the need for balanced consideration of fiber green laser pointer, fiber grating wavelength special difficulties, the noise is too large and so on. Straight and short cavity DBR type, although with high gain, can achieve higher power output and easy to implement single-longitudinal-mode output, etc., but also difficult to achieve with a strong weld, poor reliability cavity for frequency selection grating requirements more high, not easy to achieve, short straight cavity difficult to produce, difficult to adapt to the harsh working conditions and other shortcomings.

With respect to the above techniques, Shanghai Hanyu CoSF-1 single-frequency fiber laser is through "optimized traveling wave cavity" design eliminates standing waves spatial hole burning effects. Meanwhile, long cavity length is designed to allow a longer gain fiber, fully absorb the pump light, high power output; traveling wave operation significantly reduced relative intensity noise and phase noise fiber lasers. And all-fiber injection narrowband filter to select a single longitudinal mode output; long saturable absorber stable single longitudinal mode operation; single polarization control eliminates polarization hole burning, stable single polarization output polarization extinction ratio of up to 25dB or more. Phase noise, key indicators frequency noise, line width, frequency stability and power stability have reached a higher level.

Laser Printing of New Technology Into the Field of Wearable

Garment processing industry, jeans processing is a rather special processing, traditional processing technology many steps, and when performing special processing operations, there will be a lot of uncertainty. This gives a lot of want to produce high-quality jeans manufacturers to bring no small problem. Italy SEI 30000mw laser pointer processing equipment redefinition of denim jeans processing technology, in many areas to reduce the many uncertainties and simplifying the relevant procedures to eliminate unnecessary process steps, reducing resource consumption, reduce pollution emissions and the effect on the final show did not disappoint.

3D laser printing device combines the depth of information technology and manufacturing technology, while scanning the laser 4, which is currently the world leader in high-precision metal parts 3D laser printing device.

Jeans processing traditional process more costly and time-consuming and labor-intensive costs due to the new environment in the background, the state has increased the standard of energy saving, to let more companies to participate, so the production of traditional manufacturing industry will face a transition problem. The advent of new high-tech 20000mw blue laser printing equipment for many manufacturers is undoubtedly good news, it is energy-efficient features speak costs in the processing industry continue to spread, and after the information processing precision laser processing technology also allows the original complex there is a risk of jeans process better.

For this reason, the fashion designer who can develop their own unlimited brain hole to design jeans and other clothing design, because the garment laser processing equipment already has such a condition, but also has the ability to mass production, so "boom" become more simplistic.

Jeans burning laser printing equipment can make a lot of style effects, such as 3D three-dimensional printing, complex ethnic totem, holes, burning flowers, and so do the old effect, this new technology of laser processing Cowboys will continue as the market promotion and influence force gradually spread, the jeans will be the future mainstream mechanical processing field use.
