Single Synthetic Crystal Quartz
Our Single Synthetic Crystal Quartz products are popular in the market. Single Synthetic Crystal Quartz SiO2 is grown by hydrothermal method in autoclaves. It is a kind of nonlinear optical materials called a kind of birefringent crystal. It has trigonal crystal structure with right-handed or left-handed modification. Quartz crystals have low stress birefringence and high refractive index homogeneity. The optical transmission range of crystal quartz is 0.2-2.5microns. It is mentioned that Very thin Crystal Quartz SiO2 Wafer are available from Coupletech.

Neodymium Doped Gadolinium Orthovanadate (Nd:GdVO4 crystal)
Our Neodymium Doped Gadolinium Orthovanadate (Nd:GdVO4 crystal) is well received in the market. Neodymium doped Gadolinium Orthovanadate single crystal ( Nd:GdVO4 crystal ) is an excellent Laser Crystal. This kind of Optical Crystal is ideal laser host material for the DPSS ( Diode pumped Solid State ) micro/mini lasers as its good physical, optical and mechanical properties. It has higher slope efficiency than Nd:YAG and better thermal conductivity, higher power output than Nd:YVO4 Crystals, so it is a good choice to use Nd doped Gadolinium Orthovanadate Single Crystal for high power output laser dioed pumped solid state lasers. Nd:GdVO4+YVO4 Diffusion Bonded Crystals from Coupletech can be available.

Diffusion Bonded Composite DBC Laser Crystal
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.

Infrared ZnGeP2 (ZGP) Crystal
Our Infrared ZnGeP2 (ZGP) Crystal products are your best choice! Infrared ZnGeP2 (ZGP) crystals have transmission band edges at 0.74 and 12 µm. However their useful transmission range is from 1.9 to 8.6 µm and from 9.6 to 10.2 µm. IR Nonlinear Crystal ZnGeP2 have the largest nonlinear optical coefficient and relatively high laser damage threshold. NLO Crystals ZGP crystals can successfully be used in diverse applications: Up-conversion of CO2 and CO laser radiation to near IR range via harmonics generation and mixing processes, efficient SHG of pulsed CO, CO2 and chemical DF-laser, and efficient down conversion of Holmium, Thulium and Erbium laser wavelengths to mid infrared wavelength ranges by OPO process.

Passive Q-Switch Crystal Cr:YAG
We have many years of experience in the production of Passive Q-Switch Crystal Cr:YAG. 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.
