Laser Parameters

This paper studies of laser parameters for color marking on AISI 304 stainless steel by using Nd:YAG laser. Different laser parameters can affect metal color profoundly. The experiment focuses on some key parameters, and their optimum laser parameters are as follows: the vector step 0.005mm~0.010mm, the inter-step time 35μs~60μs, laser Q frequency 2KHz~4KHz, laser Q release time 10μs~20μs, scanning space 0.006mm~0.010mm. It is of significance in guiding practical application of laser color marking.
