Defect-related absorption and luminescence have been discovered and a method to reduced them was suggested. The Digital construction, density of states, plus some optical Homes were calculated from the 1st ideas for Li2In2GeSe6. Calculated nonlinear coefficients and rather substantial birefringence show a solid stage-matching means. These investigations exhibit that Li2In2GeSe6 is a promising mid-infrared nonlinear optical crystal.
Preliminary experiments have indicated that this stoichiometry-dependent mid-IR absorption in AgGaSe(2) crystals could possibly be considerably minimized by optimization of the method parameters all through crystal advancement and annealing.
(LIDT) and optical birefringence is The real key to get the excellent NLO crystals for harmonic mid-IR coherent
