Physical, chemical and optical properties of barium nitrate Raman crystal

The physical, chemical and optical properties of barium nitrate crystal are considered from the point of its application for development of solid stat e Raman lasers and shifters. The described growth procedure has shown the p ossibility to fabricate laser elements with high optical homogeneity. Using Raman spectroscopic investigation of vibronic modes in barium nitrate crys tal the linewidth broadening and frequency shift were measured. This proved that internal Raman modes in barium nitrate crystal have weak couplings wi th lattice phonons that results in high gain of Stimulated Raman Scattering (SRS).
