1. An improved three-dimensional two-temperature model for multi-pulse femtosecond laser ablation of aluminum was proposed and tested.
2. The model can predict the depth and radius of drilled holes accurately when using different laser parameters.
3. Multi-pulse ablation threshold is much lower than single-pulse one, which will help to obtain high-quality holes.
The article provides a detailed description of an improved three-dimensional two-temperature model for multi-pulse femtosecond laser ablation of aluminum, which has been tested in experiments and found to be able to predict the depth and radius of drilled holes accurately when using different laser parameters. Additionally, it was found that the multi-pulse ablation threshold is much lower than single-pulse one, which will help to obtain high-quality holes.
