DETAILS, FICTION AND BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−one phonon corresponds for the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful concept computations exhibit that the residual absorption from the BGSe crystal or

AgGaS2(AGS) crystal is one of the most effective nonlinear laser crystals used in the infrared Doing work band At this time. Because of its massive nonlinear coefficient, large infrared transmittance, small optical absorption and scattering, and very low wavefront distortion performance, its application inside the infrared field continues to be pop
