Cr4+:YAG Crystals
Description
Cr4+:YAG(Chromium-doped Yttrium Aluminum Garnet ) is a passive Q-switch crystal which is widely used on Nd:YAG, Nd:Ce:YAG, Nd: YLF, Nd:YVO4, Yb:YAG lasers at wavelength of 800nm~1200nm. The Passive Q-switches or saturable absorbers can provide high power laser pulses without EO Q-switches.
