Defect-related absorption and luminescence ended up unveiled and a method to decreased them was prompt. The electronic construction, density of states, and some optical Attributes were being calculated from the main rules for Li2In2GeSe6. Calculated nonlinear coefficients and fairly massive birefringence reveal a robust stage-matching capability. These investigations display that Li2In2GeSe6 is actually a promising mid-infrared nonlinear optical crystal.
Preliminary experiments have indicated that this stoichiometry-dependent mid-IR absorption in AgGaSe(2) crystals may very well be considerably lessened by optimization of the process parameters in the course of crystal advancement and annealing.
