provides a large absorption cross section in the 0.9-1.2 micrometer
spectral region, which makes it an attractive choice as a passive
Q-switch for the diode or lamp pumped Nd:YAG, Nd:YLF, Nd:YVO4, Yb:YAG
lasers. Cr4+:YAG has high damage threshold, good thermal conductivity,
good chemical stability and is resistant to ultraviolet radiation.
Cr4+:YAG can be also used for tunable lasers with output adjustable
between 1350-1550 nm. It can generate ultrashort pulses when pumped at
1064 nm by a Nd:YAG laser.
