Optical properties of nonlinear solid solution GaSe(1-x) S (x) (0 < x a parts per thousand currency signaEuro parts per thousand 0.4) crystals

Abstract

Transmission spectra and phase matching conditions for second harmonic generation in GaSe(1-x) S (x) (0 < x a parts per thousand currency signaEuro parts per thousand 0.4) solid solution crystals are experimentally investigated. An algorithm is suggested and dispersion equations are derived that allow the phase matching angles describing best the available experimental data to be estimated as a function of the mixing ratio x.
