Ti sapphire laser crystal

Titanium-doped sapphire (Ti3+:sapphire) as an optically pumped, solid-state laser crystal is widely used in wavelength tunable laser which tunable range is 650-1100nm, and peaking at 800nm, it is one of the widest wavelength tunable laser crystal. The upper-state lifetime of Ti:sapphire is short to 3.2ms, because of high saturation power, it’s hard to pump it by lamp, argon ion lasers or frequency-doubled Nd:YAG laser etc. is usually adapted. Using self-mode-locking technology, the Ti:Sapphire laser can output laser pulse with pulse width as short as 6.5fs directly, which is the narrowest laser pulse of all lasers that directly output from the resonant cavity. Through frequency-double technology, the wavelength of laser beam can cover wide band from blue to deep ultraviolet, produced 193 nm laser has been used in lithography machine.

Er:YAG laser crystal

Erbium doped Yttrium Aluminum Garnet (Er:Y3Al5O12 or Er:YAG) combine various output wavelength with the superior thermal and optical properties of YAG. It is an excellent laser crystal which lasers at 2.94μm. This wavelength is the most readily absorbed into water and hydroxylapatite of all existing wavelengths and is considered a highly surface cutting laser. It is a well known material for medical applications.

Er YAG laser Crystal—50% Erbium doped in YAG which can stimulate 2940nm laser used in medical and dentistry

The emission wavelength of Er:YAG with doping concentration of 50% is 2940nm, which is at the position of water absorption peak and can be strongly absorbed by water molecules. Therefore, it is widely used in the field of plastic surgery and dentistry. At present, the projects we have participated in include laser blood collection instrument, which adopts the structure of both sides of Er:yag rods coated and xenon lamp end pumped.the Er-YAG laser wavelength is an excellent choice for improvement of a variety of skin conditions and features of aging, including dyschromia, actinic photodamage, solar elastosis, acne and traumatic scarring, fine lines and mild to moderate rhytidosis, coarse skin texture, and skin laxity.
