CCJC's main products including bonding crystal, YLY-based crystal, YVO4 based crystal, YAG based crystal, LBO, BBO, KTP, Cr:YAG, Cospinel, Ti:sapphire, Er:Glass, YbKGW, YbKYW, TGG, CaF2, MgF2 etc. Currently, CCJC grows several crystal series in housep-LBO and BBO series; YLF based series, YVO4 and YAG based series.
Yb:YAG is more suitable for diode-pumping than the tradional Nd-doped systems. It can be pumped at 0.94um laser output. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a much larger absorption bandwidth to reduce theram management requirement for diode lasers, a longer upper-state lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications.
1) Very low fractional heating, less than 11%
2) Very high slope efficiency
3) Broad absorption bands, about 8nm@940nm
4) No excited-state absorption or up-conversion
5) Conveniently pumped by reliable InGaAs diodes at 940nm(or 970nm)
6) High thermal conductivity and large mechanical
7) High optical quality
*Slabs, thread rod, Er:YAG, Nd:YAG, Cr:YAG, Ce:YAG, Tm:YAG, Ho:YAG and other ion doped YAG crystals are also available upon request.

Optical Design
There are eight professors in our scientific research team. All of them come from Chinese Academy of Sciences, Changchun Institute of Precision Machinery and Physics. We can supply design Optical System according to your demand.
Processing & Testing
We have more than50 advanced milling grinding, polishing, plating equipments from The Unite States and Japan. And also introduced the ZYGO horizontal laser interferometer, AK100 horizontal laser interferometer, LAMBDA950 spectrophotometer, the focal length meter and other test equipments.
Optical Coating
We are coat from 0.2um to 20um. Including AR coating, high reflect film, the splitting film, laser crystal film, IR film, UV film and Optical fiber film etc. Especially in the laser, the frequency doubling crystal, IR crystal, and UV band coating we have huge advantage.
