Cr4+:YAG is an excellent crystal for passively Q-switching Nd:YAG, Yb:YAG, Nd:YVO4 and lasers at wavelength from 0.8 to 1.2 µm, it can also be used as an active media for CW, pulsed or self mode-locked tunable NIR solid-state lasers with the tunability range of 1340 - 1580 nm. Because of its chemically stable, durable, UV resistant, good thermal conductivity and being easy to be operated, it will replace traditional materials, such as LiF, organic Dye and color centers.
Advantages:
High damage threshold
Lower cost OEM components
Higher reliability & longer lifetime Providing high power laser pulses without electro-optic Q-switches
