Abstract
Phase conjugation in a Cr4+:YAG saturable absorber by degenerate four-wave mixing with nanosecond pulses at λ = 1.06 μ m is demonstrated for the first time to our knowledge. An experimental phase-conjugate energy ref lectivity of ~2% and an overall eff iciency of ~0.4% are achieved. Because of the presence of absorbing dipoles oriented along specif ic directions, it is shown that the phase-conjugated beam can be made orthogonally polarized relative to the signal beam or to both pump beams with almost no reduction of the energy reflectivity.
