Abstract

Solid-state lasers for micromaterial processing should have high average output power combined with high beam quality. To increase the beam quality we realized a flashlamp-pumped oscillator single-rod amplifier system with phase-conjugating SBS-mirror and an average output power up to 140 Watt.¹ To extend the average output power of this system we develop multirod oscillator amplifier systems with phase conjugation. In contrast to other multi-amplifier systems with SBS^2-4 we use Nd.-YALO as active material to avoid the depolarization effect resulting in a simple optical arrangement (see Fig. 1).
