We demonstrate a diode-pumped Yb-doped fiber master oscillator (Nd:YAG) power multimode amplifier. The multimode output beam is converted to singlemode by a two wave mixing process in an infrared sensitive photorefractive crystal. Up to 1 W singlemode output is achieved by compensation of thermally-induced phase fluctuations in the fiber.
