Abstract
We report on a picosecond laser system produced by grating stretcher and regenerative amplifier. Firstly, mode-locked pulses with 8.5 ps and around 160 mW at the repetition rate of 143.8 MHz were obtained by semiconductor saturable absorber mirrors (SESAM). Secondly, we successfully got the pulses stretched with grating stretcher from 160 mW and 8.5 ps to 90 mW and 99.9 ps. Finally, by using multi-pulse regeneration amplifier system we got a pulse sequence has each of five pulses as a group which output energy about 28.0 mJ at the repetition rate of 1 kHz and 1064 nm in single pulse width.
