Theory of Phase Conjugation in a Saturable Amplifier with Finite Probe Intensity

Phase conjugation in a nearly-resonant saturable laser amplifier by degenerate frequency mixing (DFM) is analyzed numerically in the strong probe limit. DFM reflectivities greater than unity are predicted for representative cases. At high pump intensity, the conjugate reflectivity with a finite probe approaches the reflectivity of the weak probe limit. At lower pump intensity, the conjugate reflectivity drops precipitously from the weak probe limit.
