Abstract

Abstract Bursts of GHz repetition rate pulses can significantly improve the ablation efficiency of femtosecond lasers. Depending on the process conditions, thermal mechanisms can be promoted and controlled. GHz ablation therefore combines thermal and non-thermal ablation mechanisms. With an optimal choice of the burst duration, the non-thermal ablation can be highly enhanced by a heating phase due to the first pulses in the burst. The GHz burst mode can be considered as a key function for the “agility” of new high-power lasers.

敏捷高功率激光GHz飞秒处理

摘要GHz重复频率脉冲的爆发可以显著提高飞秒激光器的烧蚀效率。根据工艺条件，可以促进和控制热机制。因此，GHz消融结合了热消融和非热消融机制。通过对突发持续时间的最佳选择，由于突发中的第一脉冲，可以通过加热阶段来高度增强非热消融。GHz突发模式可以被认为是新型高功率激光器“灵活性”的关键功能。
