Аннотация: 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.materials can be successfully produced both by heattreatment in furnace and by a laser irradiation and in this way treated glasses have many potential industrial applications such as optical memory devices, electro-optical frequency converters [4–8]. In the present research, bismuth–germanium oxide glasses doped with chromium were synthesized and treated by conventional heat-treatment and also by a focused femtosecond laser beam. The research was financially supported by Russian Science Foundation (Grant 14-13-01074G) and Russian Foundation for Basic Research (Grant 16-33-60081).
