Abstract

Conventional mathematical treatments of stimulated scattering are generally truncated description in the sense that the integral effects of field (pump and Stokes) induced nonlinear refraction are omitted. While such analysis is justified on the basis of steady state operation Lu and Harrison have recently shown^[1] in a more complete treatment that the interplay of nonlinear refraction with the gain of these processes leads to rich dynamical instabilities and chaos in the scattered and pump fields; omissions of dispersive effects resulting in stable emission only. Such behaviour is shown to be prevalent over broad experimentally accessible operating conditions, in some instances from the onset of stimulated scattering.
