A method of etching micro-grating structures (MGSs) on the surface of glazed stainless-steel directly was investigated, and a 532 nm diode-pumped solid-state laser (DPSSL) was used. The influences of the experimental parameters such as laser power, source beam diameter and period of grating, on the depth of grooves and duty cycle of MGSs were analyzed. The results were concluded and analyzed with conventional optical microscopy and atomic force microscopy (AFM). When the laser power and cross angle are 45 mW and 20° respectively, the best MGSs are obtained with 1.34 μm in period and 300 nm depth. Meanwhile, either increasing the grating period or the source beam diameter can enhance the depth of grooves.
