Near Threshold Behavior of Stimulated Brillouin Scattering in an Off-Axis Resonator
Toshio Ito, Hiroshi Takuma
Strong interference of the first Stokes Raman radiation with the stimulated Brillouin radiation has been observed in an off-axis resonator: Brillouin gain decreases appreciably by the presence of the Raman radiation in a medium such as CS2, in which the Raman and Brillouin scatterings can be stimulated simultaneously. Such a type of interference can be explained as the Raman scattering of the Brillouin photons stimulated by the first Stokes Raman photons. A classical theory has shown a quantitative agreement with the experiment. The anti-Stokes Brillouin components have not been observed even though the laser excitation was intense enough to allow the observation of the multiple Stokes components which were excited directly in the off-axis resonator without the feed-back effect of the laser as an amplifier.
