Abstract
We report an experimental study of Brillouin two-beam coupling in CS2 at 1.06 μm in the regime below the pump’s stimulated Brillouin scattering (SBS) threshold. Angular discrimination between the pump and signal beams is employed. No competitive self-SBS (phase conjugation) of the pump was observed despite operation near the SBS threshold. Image intensification by a factor of 300 is demonstrated with this configuration.
