Simulation of single-, double- and multi-pulse laser ablation of metals
Journal of Physics Conference Series(2019)
摘要
We present preliminary results of hydrodynamic modeling of the laser ablation of copper by femtosecond laser pulses in regimes of single-, double- and multi-pulse irradiation. It is demonstrated that in comparison to a single-pulse regime the double-pulse one with a short subnanosecond delay is less effective while multi-pulse ablation with a subnanosecond intraburst is more effective. We show that multi-pulse ablation produces deeper crater in comparison with single-pulse or double-pulse regimes of the same energy.
