从GaSe:AgGaSe2熔体(质量掺杂浓度为10%)中生长的非线性光学晶体ε-GaSe:Ag晶体(质量掺杂浓度≤0.04%)是一种非中心对称晶体,可用于相位匹配频率转换。Ag的掺入使GaSe晶体的显微硬度提高了30%,从而使其可以在任意方向上进行切割和抛光。本文研究了GaSe:AgGaSe2晶体在可见、中红外及太赫兹波段的光学性能。实验证明:GaSe:AgGaSe2晶体的吸收系数是纯GaSe晶体的2倍,其CO2激光倍频效率是ZnGeP2晶体的1.7倍。

The nonlinear optical crystal grown from the melt GaSe∶ AgGaSe2(10%,mass percent) is identified as acentrosymmetric ε-GaSe∶ Ag(≤0.04%,mass percent) and is used for phase matched frequency conversion.The silver presence results in 30% increase in microhardness,which allows the crystal to be cut and polished at arbitrary direction.The optical properties from visible to mid-IR and further THz ranges are studied in detail.It demonstrates that the absorption coefficient of GaSe∶ Ag(≤0.04%,mass percent) crystal is twice that of a pure GeSe,and the CO2 laser Second Harmonic Generation(SHG) efficiency is about 1.7 times that of ZnGeP2 crystal.
