Abstract
A quantum mechanical analysis is made of higher order processes in Raman scattering. In particular the examples of coupled Stokes and Antistokes radiation and the generation of 1st and 2nd Stokes radiation are considered. All fields, electromagnetic and phonons, are quantized and the Schrödinger equation for the system is solved exactly. This completely quantum mechanical approach eliminates discrepancies which occur when linearization procedures such as the parametric approximation are employed. The theory applies to both stimulated and spontaneous Raman scattering.
