Abstract : We demonstrate an efficient dynamical amplification of phase conjugation in the gain medium of a diode-pumped Nd3+: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 classical homodyne approach.
