Abstract
The thermal lensing effect in high-average power Nd:YAG-laser amplifie rs is compensated by stimulated Brillouin scattering in CS2. Nearly di ffraction limited laser beams with average powers above 100 Watts were obtained. The system emitted bursts of 10 to 30 pulses with 40 ns wid th. The bursts have a repetition rate of 100 Hz and a duration of 100 mu s. The beam quality degrades by depolarization effects at the highe st pump and output powers. This degradation is avoided using polarizat ion preserving Nd:YALO-laser crystals.
