The research on the hundred picosecond laser with high repetition rate and high pulse energy

We report on a picosecond pulse laser produced by grating stretcher and regenerative amplifier. By designing the experimental setup and numerical simulation, mode-locking output pulse energy of 7.5mJ with a repetition rate of 1KHz and a pulse width of 106.4ps stretched from 8.5ps is obtained at 1064nm. The results indicated that this system has laid a good foundation for the multichannel amplification to get higher pulse energy.
