Abstract
Second harmonic generation in gallium-lanthanum-sulphide (Ga:La:S) and germanium sulphide + Ga:La:S glasses is investigated. It is shown tha t microcrystals of Ga:La:S and alpha phase of gallium-sulphide (alpha- Ga2S3), whose presence in the glass matrix is revealed by energy dispe rsive spectroscopy and x-ray diffraction analysis, are responsible for the frequency doubling process.
