Product Description

Cr4+:Y3Al5O12 ( Cr:YAG ) crystal is one of the most promising passive Q switching materials for passively Q-Switching diode pumped or lamped Nd:YAG, Nd:YLF, Nd:YVO4 or other Nd and Yb doped lasers at wavelength from 0.8 to 1.2um. Because of its chemical stability, durability, UV resistance, good thermal conductivity, high damage threshold (> 500 MW/cm ) and easy operation, it will replace some traditional switching materials, such as LiF and organic Dye.


The preliminary experiments of Cr:YAG Crystals 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. Laser Crystal Chromium Doped Yttrium AIuminum Garnet Crystal (Cr4+:YAG) is an excellent crystal for Q-switches application. Passive Q-Switch Crystal Cr:YAG is common applied in scientific, medical and industrial field. Coupletech also offer Nd:YAG and Cr:YAG Diffusion Bonded Crystals.

Cr4+YAG Crystal


Coupletech provides Cr4+:YAG with Cr4+ 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 according to customers`requirements.
The preliminary experiments of Coupletech`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 as high as 10kHz for diode pumped Nd:YVO4 lasers. Furthermore, an efficient green output at 532nm, and UV output at 355nm and 266nm were generated, after a subsequent intracavity SHG in KTP or LBO, THG and 4HG in LBO Crystals and BBO Crystals for diode pumped and passive Q-switched Nd:YAG and Nd:YVO4 lasers.
Cr4+:YAG is also a laser crystal with tunable output from 1.35 µm to 1.55 µm. It can generate ultrashort Pulse Laser (to fs pulsed) when pumped by Nd:YAG laser at 1.064 µm.
