摘要:
The temporal profiles of high-power short-pulse lasers reflected from self-induced plasma mirrors (PMs) were measured with high temporal resolution in the sub-picosecond window.The leading front shape of the laser pulse is found to depend sensitively on the laser fluence on the PM surface.Spectral modulation plays a key role in pulse profile shaping.Our findings will extend our knowledge on properly using PMs.
