A 7.8W near-diffraction-limited output from a continuous-wave double-pass side-pumped Nd:YVO<sub>4</sub> amplifier with a ring self-pumped Rh:BaTiO<sub>3</sub> phase conjugate mirror is presented. The corresponding optical extraction efficiency of as much as 33% was obtained. Laser oscillation of a continuous-wave diode-pumped Nd:YVO<sub>4</sub> phase conjugate resonator is also investigated. A 7.5 W high quality output was generated. The slope efficiency of 46% was achieved.
