摘要：
A high energy 532 nm hundred picoseconds laser based on stimulated Brillouin scattering (SBS) pulse compression and second-harmonic generation (SHG) is demonstrated. The seed is single frequency laser with pulse width ins at 1064 nm delivered from a Cr4+.:YAG passively Q-switched oscillator with Fabry-Perot etalon (FPE) as a frequency selector. Master oscillator power amplifier (MOPA) and compact single-cell FC-770 pulse compressor are combined to generate high energy output with hundred picosecond pulse width. Without any breakdown of optical devices, single frequency pulses are generated with compressed pulse width less than 450 ps and maximum energy up to 400 mJ, Type-II phase matching nonlinear crystal KDP is adopted for SHG of the fundamental laser. The optical-to-optical frequency conversion efficiency reaches up to 55%. The beam quality factor M-2 is measured to be 2.45 and the output power stability is better than 3.5%.
