What is the Cr: YAG
Cr: YAG crystal, also referred to as chrome-doped yttrium aluminum garnet, is a good passive Q-switching material or saturated absorber. Cr: YAG crystals (passive Q-switches, saturated absorbent) offer high-power laser pulses without the need for electro-optic Q-switches. Such passive Q-switching products or saturated absorbers can greatly decrease the pulsed laser. And it can avoid the high voltage power supply of electro-optic Q-switches.
The application of Cr: YAG
Cr4+: YAG(chromium-doped yttrium aluminum garnet) is widely used in lasers with wavelength from 800 to 1200 nm. Cr4+: YAG (chromium-doped yttrium aluminum garnet) is extensively utilized in lasers with wavelengths varying from 800nm to 1200 nm. Such as Nd: YAG, Nd: Ce: YAG, Nd: YLF, Nd: YVO4, Yb: YAG laser. Passive Q-switches or saturable absorbers can supply high-power laser pulses in the lack of EO Q-switches.
Q-switched diode-pumped or light pumped laser
Cr4+: YAG crystals are superb crystals for easy Q-switched diode-pumped or light pumped Nd: YAG, Nd: YLF, Nd: YVO4 or other Nd and also Yb-doped lasers at wavelengths varying from 0.8 to 1.2 µm. Because of its chemical stability, longevity, UV resistance, great thermal conductivity and high damages threshold (> 500 MW/cm2) along with convenience of procedure. It is replacing much more traditional q-switching materials such as lithium fluoride, organic dyes, and color centers.
Chromium (IV) -doped YAG (Cr: YAG) provides a huge absorption random sample in the 0.9-1.2 micron spooky region. Which makes it an attractive selection for easy Q-switching in ND-doped lasers. The resulting tools are solid-state, small as well as low-priced. It has high damages threshold, excellent thermal conductivity, excellent chemical stability, UV radiation resistance, as well as very easy processing.
It can be utilized passively to perform easy Q-switching on pumped Nd: YAG, Nd: YLF, Nd: YVO4, Yb: YAG as well as various other ND-doped lasers with wavelengths between 1000 and 1200 nm for diodes or lights.
Cr: YAG can likewise be used for tunable lasers whose result is tunable between 1350 as well as 1550 nm. When the Nd: YAG laser is pumped at a price of 1064 nm, it can produce ultra-short (as reduced as femtosecond array) pulses.
Cr: YAG has actually been received nonlinear optical applications to be a self-pumping phase-conjugate mirror in a Nd: YAG loophole resonator. It provides compensation for stage and polarization aberrations induced in the loophole resonator.
