Chromium(IV)-doped YAG (Cr:YAG) 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 Nd-doped lasers.

The resulting devices are solid-state, compact and low-cost. It has high damage threshold, good thermal conductivity, good chemical stability, is resistant to ultraviolet radiation, and is easily machined. It is replacing the more traditional Q-switching materials like lithium fluoride and organic dyes. The dopant levels range between 0.5-3 molar %.
It can be used for passive Q-switching the diode or lamp pumped Nd:YAG, Nd:YLF, Nd:YVO4, Yb:YAG, and other neodymium and yttrium doped lasers at wavelengths between 1000-1200nm.
Cr:YAG can be also used for tunable lasers with output adjustable between 1350-1550nm. It can generate ultrashort (down to femtoseconds range) pulses when pumped at 1064nm by a Nd:YAG laser.
