Chromium-Doped Yttrium Aluminum Garnet
Cr4+:YAG is an excellent passive Q-switch crystal widely used in 1μm neodymium and ytterbium lasers. It offers high Q-switched output efficiency and suitability for repetitive operation. Its high optical damage threshold and greater stability and durability than dye or color-center saturable absorbers allow it, in some cases, to replace electro-optic Q-switches for high-power laser pulse output.
