New Step by Step Map For AgGaSe2 Crystal
Blog Article
Defect-related absorption and luminescence had been revealed and a way to decrease them was instructed. The Digital structure, density of states, and a few optical Attributes had been calculated from the first principles for Li2In2GeSe6. Calculated nonlinear coefficients and alternatively massive birefringence point out a powerful stage-matching means. These investigations display that Li2In2GeSe6 is often a promising mid-infrared nonlinear optical crystal.
Preliminary experiments have indicated that this stoichiometry-dependent mid-IR absorption in AgGaSe(two) crystals may be substantially lessened by optimization of the procedure parameters for the duration of crystal advancement and annealing.
