Photorefractive phase conjugate resonators (PPCR), in which one end mirror is a self- pumped photorefractive phase conjugate mirror (PCM), have received an intense attention, because of its correction of thermal distortions in the laser resonator and laser oscillation without external pumping beams to the PCM.1,2 However, until now, there is no report concerning PPCR 1 μm lasers. In this paper, we report the first demonstration, to the best of our knowledge, of a continuous-wave (CW) operation of a diode- pumped Nd:YVO4 phase conjugate resonator based on a Rh:BaTiO3 phase conjugate mirror. A 7.5 W output with high beam quality was obtained.
