Abstract
In high-power laser system, in order to extend the components' service life and reduce the operation costs, more attentions should be pay at the research for damages ablation at multi-layer optical components and other high load optical components. 240ps, 35ps, 6ps 1053nm laser pulses has been used to investigate damage ablation and damage resistant experiments at 0° high reflection films. By comparing the damage morphology and damage resistant threshold of the ablation pits at different pulses width, it was superior to use ultra-short pulse to repair multi-layers optical components. It was found that the shorter pulse width has been used, the higher the damage resistant threshold and the lower the laser modulation. Furthermore, the finite-difference time-domain method was used to simulate the electric-field intensification within the large size damage region of multilayer films.
