  • Numerical simulation for temperature field and crater on the laser ablation in laser micro-texture sculpt was performed by means of finite-difference method.Based on energy conservation equation,Gaussian distribution of the incident laser pulse was taken into account in the numerical model.The distribution of the temperature field of the target in the laser micro-texture sculpt was simulated and so were the depth and diameter of the crater.The simulated results were compared with the experiment before.The former accorded well with the latter.This study established the basic theory in laser micro-machining.
