Abstract :
Summary form only. This work investigates the build-up of phase conjugation SBS in a fiber in the case of excitation by a long pulse. The source of pump radiation was a single longitudinal and transverse mode CW Nd:YAG laser. A mechanical chopper produced pump pulses with a rectangular waveform of 750 /spl mu/s duration and rise-time 2 ps.
