Abstract
A transient model of degenerate four-wave mixing in saturable amplifie rs is developed for calculation of the phase-conjugate reflectivity in the weak-probe-beam limit. Our model takes into account the laser amp lification of all the interacting beams together with the wave-mixing process between the two counterpropagating pump waves. Experimental in vestigations are made in a flash-lamp-pumped Nd:YAG amplifier with nan osecond pulses at 1.06 mum. A reflectivity of 22% is achieved when all the waves interfere within the laser medium.
