Introduction
Cr4+:YAG
(Y3Al5O12) is an ideal
material for passive Q-switching of Nd:YAG and other Nd
and Yb doped lasers in the wavelength range of 0.8
to 1.2 mm. One
of the remarkable features of Cr4+:YAG is high damage threshold
of 500-1000 MW/cm2. Passive
Q-Switching is preferred for simplicity of manufacturing
and operation, low cost and reduced system size and weight.

The preliminary
experiments of Cr:YAG showed that the pulse width of passively
Q-switched lasers could be as short as 9 ns for diode pumped
Nd:YAG lasers and repetition as high as 10kHz for diode
pumped Nd:YVO4 lasers.
Furthermore, an efficient green output @ 532 nm, and UV
output @ 355 nm and 266 nm were generated, after a subsequent
intracavity SHG in KTP or LBO, THG and 4HG in LBO and BBO
for diode pumped and passive Q-switched Nd:YAG and Nd:YVO4 lasers.
