Optical properties and application of GaSe：AgGaSe_2 crystal
摘要
Abstract
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.关键词
