Phase conjugate wavefront generation by forced Rayleigh scattering

Phase conjugate wavefront generation with efficiency up to 4% at 355 nm has been demonstrated in liquid media containing nonsaturating absorbers. Experimental results are qualitatively consistent with a simple theory of transient forced Rayleigh scattering which predicts the efficiency to depend upon the solvent, the square of the pump intensity and upon the beam quality but not upon the absorbing species. © 1982 Springer-Verlag.
