Micromachining of copper by femtosecond laser pulses

▸ We have reported new experimental and theoretical results on the femtosecond laser ablation for copper at fluences up to 408 J/cm2. ▸ The present model simulations correlate well with the experimental data over a broad range of laser fluences from 0.8 to 400 J/cm2. ▸ The good correlation suggests that the proposed model is an efficient and accurate tool for predicting ultrafast laser material ablation.
