SYNTHESIS OF TITANOSILICATE GLASS IN A ST EADY LASER FLAREE

Samples of titanosilicate glasses were synthesised by the method of la ser distillation in an atmosphere of air or nitrogen at normal pressur e. An investigation of the homogeneity of the dopant distribution in t hese samples was used to determine the dependence of the degree of ste adiness of the distillation process on the chemical composition of the components of a laser target. The components were rods or tubes made of silica glass and the dopant source was Ti foil or TiO2 powder. The Raman and optical spectra were used in a study of the phase compositio n and the Ti ion valence. The dopant mass concentration in the amorpho us samples, limited by the maximum intensity of the CO2 laser radiatio n sed in the synthesis, reached similar to 10% in terms of the TiO2 co ntent. The doping of the grown samples was homogeneousto within +/-1% throughout the investigated range 3-10% of the TiO2 concentration.
