03 Feb 2009 LaserMa provides Cr4+:YAG with different doping level. The size could be up to 16×16mm2 with variable length. Initial transmission from 10-92% according to customers’ requirements. Cr4+:YAG Crystal is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd and Yb doped lasers at wavelength from 0.8 to 1.2 µm.
The preliminary experiments of LaserMa’s Cr4+: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 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.
Cr4+:YAG is also a laser crystal with tunable output from 1.35μm to 1.55μm. It can generate ultrashort pulse laser (to fs pulsed) when pumped by Nd: YAG laser at 1.064μm. |
