Laser Material Research

     We has achieved unparalledled success in the developing mid-infrared nonlinear laser crystals Zinc Germanium Phosphide crystals (ZGP) : Record  ZGP single crystals with dimensions of 55mm in diameter and 130mm in length  have been grown by Vertical gradient freeze technique. Meanwhile, we have grown high optical quality single crystals with dimensions of Φ31×160mm using horizontal gradient freeze method . ZGP-OPO devices realized an high-power infrared laser output with a conversion efficiency reaching to 56.2%;

     Nd:YAG laser transparent ceramic have been also successful prepared by solid vacuum sintering, which had been realized an laser output at wavelength 1064nm.
