Abstract

This study proposes an approach for determining the lateral displacement distance between adjacent scanning paths for femtosecond laser ablation of a uniform crater profile on stainless steel with a controllable ablation depth. The first step performs the ablation experiment and measures the ablation depth. The second step calculates the laser intensity accumulation factor according to different lateral displacement distances. The required lateral displacement distance needed to achieve the design ablation depth can be obtained based on the experimental data.
