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.
