Paper Abstract

Stimulated Brillouin scattering phase conjugation (SBS-PC) in the fluorocarbon liquid FC-77 is investigated within the development of a single-frequency Nd:YAG master oscillator power amplifier system operating at 1064 nm wavelength. Focusing of the pulsed Nd:YAG laser radiation into a FC-77-filled SBS cell which acts as a phase conjugate mirror in a double-pass amplifier arrangement generates high peak power output radiation in the MW range. As a result of the SBS phase conjugation process, we observed an improvement of the spatial beam quality (M2 = 1.4) as well as pulse shortening to the sub-nanosecond regime (<800 ps). The latter is significantly governed by the pump energy and the focusing conditions.
