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.
Nd:YVO4 crystal is one of the most promising commercially available diode pumped solid state laser materials, especially for low to middle power density. This is mainly for its higher absorption and emission features than Nd:YAG crystal. Pumped by laser diodes, Nd:YVO4 crystal has been incoporated with high NLO coefficient crystal (LBO, BBO or KTP) to frequency-shift the output from the near infrared to green, blue or even UV.
1) Low lasing threshold and high slope efficiency
2) Low dependency on pumping wavelength and strong tendency to single mode output
3) Large stimulated emission cross-section at lasing wavelength of 1064nm
4) High obsorption over a wide pumping wavelength bandwidth
5) A uniaxial crystal with large birefringence emit linearly-polarized laser
*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.
