Cr:YAG Crystal

Cr: Y3Al5O12 crystal is one of the most promising passive Q-switching materials for passively Q-Switching Nd or Yb lasers at wavelength from 0.8 to 1.2um.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 rate as high as 10kHz for diode pumped Nd:YVO4 lasers. Furthermore, an efficient green output @532nm,and UV output @355nm and 266nm 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.
