Cr⁴YAG

Classification:

Laser crystal

Chromium-doped yttrium aluminum garnet (Cr4 :YAG) is an excellent crystal for passive Q-switching of erbium-doped neodymium yttrium aluminum garnet, neodymium-doped YLF, neodymium-doped yttrium vanadate, and other neodymium-doped or ytterbium-doped lasers with wavelengths of 0.8-1.2 μm. Sufficient laser pulses are obtained by passive Q-switching or saturable absorbers without electro-optical switching. The size is thus reduced and the need to provide high pressure energy is eliminated. It will replace the commonly used LiF and dyes in the field of passive Q-switching and become an ideal choice for 1um Nd-doped lasers.
