Stimulated-Brillouin-Scattering (SBS) provides passive Q-switching of a Nd:YAG-laser. Mode-coupling was actively supported by an AOM. Numerical simulations based on spectrally resolved rate equations including SBS-Stokes-shift and mode-locking explain special spectral features of this laser.
Summary form only given. The use of phase-conjugating mirrors facilitated a significant improvement in the performance of solid state lasers by compensating phase distortions from highly pumped laser rods. With master-oscillator double pass amplifier (MOPA) rod system average output powers of more than 100 Watts were reported. For industrial micromachining or marking average output powers of several...
