Leistungsgrenzen der Phasenkonjugation fuer Hochleistungs-Festkoerperlaser Abschlussbericht

Abstract

In the frame of the present project oscillator and oscillator-amplifier systems with phase conjugating SBS (stimulated Brillouin scattering)-mirrors for better beam quality and higher output energy have been optimized. In designing Nd-solid state master oscillator double pass amplifier setups with almost diffraction limited beam quality, with 102 W average output power the world wide leading values could be reached. The developed systems with single laser rods instead of SLABs and the necessary additional devices for beam shaping and multipasses are much cheaper for the same performance than international competitors. The new systems with almost diffraction limited beam quality produced by the compensation of phase distortions via phase conjugating SBS-mirros allow for new applications as a consequence of their higher brightness compared to todays available commercial systems.
