Cr4+ Yag laser crystal rod (Yttrium Aluminum Garnet doped with Chromium)
Cr 4+ :YAG is one of passive Q switch crystal in our company.
Cr 4+ :YAG showed that the pulse width of passively Q-switched lasers could be as short as 5ns for diode pumped Nd:YAG lasers and
repetition 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.
Crystro has perfect automatic production equipment, the current products are mainly concentrated in the YAG, MgAl2O4,TGG, TSAG,GGG, LGS, Ce:GAGG , Ce:YAG andCe: LuYAG production. the application of advanced process technology of manufacturing, reducing energy consumption to ensure sustainable development field of research and development.
Crystro's Cr4+:YAG has advantages:
High chemical stability and reliability and High damage threshold (>500MW/cm2) and Long lifetime and good thermal conductivity
