摘要：

Microlens formation, as induced by single shot of a femtosecond laser pulse, was observed in Sm-doped non-crystalline SrS-Ga2S3 thin films. The existence of Sm2+ could be related to the photoinduced deformation of the thin films. The confocal scanning laser microscopy observations revealed that detachment in the thin films occurred locally at the center part of the irradiated area.
