We have designed a compact solid compressor by stimulated Brillouin scattering (SBS), which consists of two right angle prisms and a fused silica glass block. A 13–16 ns Nd:YAG laser pulse has been temporally compressed to 1 ns or less phase conjugation pulse in a fused-quartz and fused-silica glass at four different wavelengths. Maximum reflectivity of SBS was 90–95% without damage. The brightness of the compressed pulse was about ten-fold higher than that of the incident pulse. Damage-free operation using fused quartz glass as a better phase conjugation material could lead to the construction of a more compact, laser-diode-pumped, and all-solid-state laser system.

Stimulated Brillouin

The thermal lensing effect in high-average power Nd:YAG-laser amplifiers is compensated by stimulated Brillouin scattering in CS 2. Nearly diffraction limited laser beams with average powers above 100 Watts were obtained. The system emitted bursts of 10 to 30 pulses with 40 ns width. The bursts have a repetition rate of 100 Hz and a duration of 100 µs. The beam quality degrades by depolarization effects at the highest pump and output powers. This degradation is avoided using polarization preserving Nd:YALO-laser crystals.
