In this article a new mathematical model for a laser metal ablation by ultra-short duration laser pulses is proposed. The computational process is based on a two-temperature hydrodynamic model for electrons and ions. Some improvements are made and wide-range equation of state for metals is included in model. The results of the computer simulation of ablation depth for aluminum and copper are compared with experimental data at a different laser fluency values. We obtained a good agreement between the experimental and calculated data on the ablation depth.
