title: Dynamical amplification of phase conjugation using a modulated optical feedback in a Nd:YVO4 laser.
abstract: We demonstrate an efficient dynamical amplification of phase conjugation in the gain medium of a diode-pumped Nd(3+)YVO4 solid-state laser via excitation of its relaxation oscillations. Consequently, enhancement in the modulated amplitude of the phase conjugate wave is observed with up to +30 dB compared to the classical homodyne approach.
