Our Diffusion Bonded Composite DBC Laser Crystal products have been recognized by our customers with advanced production technology and good quality. Coupletech also provides a various of diffusion bonded Composite Laser Crystal, such as Nd:YVO4 + YVO4, YVO4 + Nd:YVO4 + YVO4, Nd:YAG + Cr:YAG, Yb:YAG + Cr:YAG, Nd:YAG + YAG crystal, etc. Diffusion-bonded Crystal technology is to make two or three pieces of laser crystal with the same crystal substrate close together to form the optical cement at room temperature after a series of treatment, and then heat-treated crystal to form a permanent bonded without the case of other binders, and thermal lens effect can be reduced by diffusion-bounded technology.

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.
