Abstract

We have found that the amount of pulse compression increases as single mode laser intensity approaches the stimulated Brillouin scattering (SBS) threshold in Hexane at 355 nm. Using an avalanche photodiode, transient digitizer, and waveform analysis, we also found that the temporal and spectral structure of SBS pulses replicated multimode pump pulses. However, during pump mode beating intensity spikes of short duration and high power, competing effects (perhaps stimulated Raman scattering) depleted gain from SBS. To our knowledge, this is the first direct temporal measurement of partial pulse replication in SBS due to mode beating.
