Abstract

Stimulated scattering is a nonlinear process that often results in the generation of a backwardgoing signal. This signal is known to display several unique and interesting properties; perhaps the most notable is phase conjugation. Stimulated Rayleigh-wing scattering (SRWS)1'2 is the stimulated scattering process arising from the optical Kerr effect, and it possesses an extremely fast response time (2 ps in CS2). Under certain experimental conditions, SRWS is known to conjugate both the phase and polarization of an incident field.3 The optical Kerr effect also leads to an intensity-dependent refractive index and is often the dominant contribution to this effect. With a large nonlinear index change, several undesirable effects, such as self-focusing and filamentation,Stimulated scattering is a nonlinear process that often results in the generation of a backwardgoing signal.
