Paper Abstract

High power Nd:YAG laser beam with wavelength 1064nm, pulsewidth 10 picosecond regime was focused onto the scanning targets of SUS304 stainless steel with Zn coating of thickness 21 micrometers , and delivered via a step index fused silica optical fiber of length 3m and core diameter 1mm. Irradiation ablation effect and some basic aspects of high power laser beam transporting in optical fiber were studied. Ablation rate was defined as ablated volume to laser fluence and used as a description of ablation cleaning ability which was investigated by means of ablated profile measurement, ablation rate calculation, chemical composition analysis of ablated area.
