Abstract
This paper presents a Ti-Sapphire-based laser amplification system in which the technique of a chirped- pulse- amplification is used. It consists of a laser oscillator, a pulse strecher,a regenerative amplifier and a pulse compressor. The laser oscillator is a home-made self-mode-locked(SLM) Ti-sapphire (3mm long) oscillator. The oscillator pumped by 5W of cw all line Argon laser can generate Forier-transform-limeted sub-20fs duration pulses at a 91MHZ repetition rate, a center wavelength of 800nm,a FWHM bandwidth of a spectrum of 80nm. The seed pulses from the oscillator are stretched by a factor of 1000 with a four-pass grating stretcher at first. After stretching, these pulses are seeded into a Ti-sapphire regenerative amplifier pumped by a frequency-doubled Q-switched a Nd:YAG laser at õKHZ.We have obtained single-pulse energy of 100 \L J, pulse duration of 50fs at the repetition rate of 5KHZ.
