Abstract

Multiple-short-pulse stimulated Brillouin scattering (MSP SBS) is a means to obtain phase-conjugation of pulse trains characterized by pulse durations and inter-pulse separations both short relative to the Brillouin lifetime. The Brillouin lifetime of the SBS medium provides a memory for pulse-to-pulse build-up of the acoustic grating. For these short-pulses and for pulse energies below the thresholds of competing non-linearities, a single pulse by itself would not be above threshold. It is the cumulative addition of in-phase acoustic gratings created by successive pulses that results in the above-threshold operation required for the high reflectivities observed.
