New physical explanation of phase-conjugate waves produced in backward stimulated scattering
Abstract
A new physical explanation is given of the process whereby backward simulation scattering (BSS) produces phase-conjugate (PC) waves. It is believed that what is happening in this process is that there are two nonlinear processes simultaneously present: a pure stimulated scattering process and a partial degeneration four-wave mixing-frequency phase-complex conjugate process. The tight coupling of these two processes makes the BSS wave possess, to a certain degree, the features of a phase conjugate to the incident wave. Experimentally, a detection method for four-wave mixing frequency was adopted and confirmed the theoretical results.
