Phasing of two-channel cw master-oscillator-power-amplifier beams by using a phase-conjugate mirror has been demonstrated for the first time to the best of our knowledge. Phasing was achieved with two fiber amplifiers in conjunction with a single-frequency Nd:YAG master oscillator by using a fiber phase-conjugate mirror in a double-pass geometry. The successful demonstration of phasing of two cw amplifier beams with a fiber phase-conjugate mirror greatly enhances the prospects for phasing of multiple laser amplifiers without complex servo-loop control systems.
