Description

technical field [0001] The invention relates to ultra-short and ultra-intensive laser pulses, in particular to a device and method for generating ultra-short and ultra-intensive laser pulse trains with high repetition frequency. Background technique [0002] At present, most of the ultra-short and ultra-intensive desktop laser devices built based on chirped pulse amplification (hereinafter referred to as CPA) technology in the world are mainly Ti:Sapphire laser systems. The technology of the ultra-short and ultra-strong Ti:sapphire laser device based on CPA technology is very mature, and its overall structure has been standardized: it consists of a self-mode-locked laser oscillator, a Faraday (Faraday) optical isolator, a laser pulse stretcher, and Ti:sapphire regeneration. Amplifier (capable of outputting 10Hz or up to hundreds of kHz laser pulses), single pulse selector, multi-pass Ti:Sapphire laser amplifier chain and multiple 532nm pump lasers with output repetition freq...
