Effect of signal frequency on four-wave mixing through stimulated Brillouin scattering

Abstract
We present measurements of the dependence of the phase-conjugate reflectivity on signal frequency for Brillouin-enhanced four-wave mixing at pump intensities above the threshold instability. The measurements were made in TiCl4 at λ = 1 μm and are consistent with a computer model of the reflectivity. We have observed that the frequency of the conjugate beam is independent of the frequency of the input signal beam in the unstable regime.
