Investigations on the ablation of steel and copper with femtosecond laser pulses using single pulses and bursts of infinite sequence of pulses with 1 GHz intraburst repetition rate are presented in this paper. The ablation efficiency is compared to the case of single femtosecond laser pulses. Based on the literature a model of the ablation process is presented explaining the behavior of a pulse burst and the good qualitative agreement of the numerical and experimental ablation efficiencies is obtained.

在GHz突发模式下使用飞秒激光脉冲对钢和铜进行激光微加工

本文对飞秒激光脉冲对钢和铜的烧蚀进行了研究,该脉冲使用单脉冲和具有1 GHz突发内重复率的无限脉冲序列突发进行。将消融效率与单个飞秒激光脉冲的情况进行比较。基于文献,提出了一种烧蚀过程的模型,该模型解释了脉冲猝发的行为,并获得了数值和实验烧蚀效率的良好定性一致性。
