Product Description


Passive Q-switching of Nd:YAG Cr4+:YAG Crystal

Cr4+:YAG Crystal is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Nd:YVO4 or other Nd and Yb doped lasers at wavelength from 0.8 to 1.2 µm. Because of its chemically stable, durable, UV resistant, good thermal conductivity and high damage threshold (> 500 MW/cm2) and being easy to be operated, it will replace traditional materials, such as LiF, organic Dye and color centers.

BrandNew provides Cr 4+ :YAG with Cr 4+ doping level from 0.5mol% to 3mol%. The size could be from 2×2mm2 to 14×14mm2 with length from 0.1mm to 12mm available. We can control the initial transmission from 10% to 92% according to customers' requirements.

The preliminary experiments of Brandnew's 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. Cr 4+ :YAG is also a laser crystal with tunable output from 1.35 µm to 1.55 µm. It can generate ultrashort pulse laser (to fs pulsed) when pumped by Nd:YAG laser at 1.064 µm.

Note：
When ordering Cr 4+ :YAG crystal, please specify the size, initial transmission and coatings. For further information, please
