New nonlinear AgGaGeS/sub 4/, AgGaGe/sub 5/S/sub 12/, AgGaGe/sub 1.5/Se/sub 5/, AgGaGe/sub 5/Se/sub 12/ and HgGa/sub 2/S/sub 4/, Cd/sub 0.35/Hg/sub 0.65/Ga/sub 2/S/sub 4/ crystals

摘要

Optical linear and nonlinear properties of a number of new nonlinear crystals are investigated for the first time. AgGaGeS/sub 4/, AgGaGe/sub 5/S/sub 12/, AgGaGe/sub 1.5/Se/sub 5/, AgGaGe/sub 5/Se/sub 12/, are solid solutions of AgGaS/sub 2/:GeS/sub 2/(Se/sub 2/) or mixed Ag/sub x/Ga/sub x/Ge/sub (1-x)/S/sub 4/(Se/sub 4/) crystals, and also HgGa/sub 2/S/sub 4/, and Cd/sub 0.35/Hg/sub 0.65/Ga/sub 2/S/sub 4/ are studied. Ag/sub x/Ga/sub x/Ge/sub (1-x)/S/sub 4/(Se/sub 4/) biaxial crystals belong to mm2 point group symmetry, transparent in the range 450-13500 nm, are characterized with n/sub y//spl ges/sub x/
