| Abstract: | With the irradiation by femtosecond (fs) laser with high repetition rate, GeS2 micro/nano-crystalline formation and microstructural modification occurred in pseudo-binary GeS2–In2S3 glass, while almost no similar change was observed in GeS2 glass. The addition of In2S3 is beneficial for the precipitation of GeS2 micro/nano-crystals. It is expected that functional micro/nano-crystals can be controllably prepared in chalcogenide glasses by fs laser irradiation through glass composition design. |
