| Popis: |
The scheme of phase conjugation (PC) in four-wave mixing with feedback (FWMF) using an amplifier in the feedback loop is a laser controlled by an external optical signal. Note that in this scheme the generation is, generally, developed simultaneously in two directions and is withdrawn through a nonlinear medium as the useful reflected wave E r counter to the signal and the parasitic wave E p copropagating with the signal. The energy of the parasitic wave E p often proves to be higher than the energy of the reflected wave E r .1,2 Thus, the problem of providing the unidirectional propagation of the conjugate wave is urgent. |
