The fabrication method by nanosecond laser technology for micro-grating is investigated in this paper. A nanosecond laser system is established and the mechanism of laser processing on material surface is theoretically analyzed. The damage threshold of stainless steel is obtained experimentally when the nanosecond laser irradiates on the specimen’s surface and the influence of the laser pulse energy to the fabricated micro-gratings are also studied. In the end, micro-gratings with high-quality are provided to validate the feasibility of the fabrication method by nanosecond laser technology.
