Optical properties transformations under heat and laser treatment of glasses in the Bi–Ge–O system
Source abstract
Abstract
Chromium-doped bismuth–germanium oxide glasses with molar composition x Bi2O3–(100 − x) GeO2–y Cr2O3 (x = 40, 50; y = 0, 0.01) were synthesized by melt-quenching technique and their physical properties were investigated. The glasses were transformed to glass ceramics by heat-treatment. The femtosecond laser-induced modification of glasses showed no glass devitrification up to the pulse energy of 400 nJ but the refractive index for all studied glasses increased on the order of 10−3. Structural and optical properties of the glasses and glass–ceramics were analyzed by X-ray diffraction, optical microscopy, and optical spectroscopy.
