Applications:
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.
CRYSTIK‘s Cr：YAG is featured by：
● High chemical stability and reliability.
● Easy to be operation
● Long life time and good thermal conductivity
● High damage threshold (>500MW/cm2)
● As high power, solid state and compact passive Q-Switch
