摘要
The multimode and depolarized output beam of a highly multimode diode-pumped Yb-doped fiber amplifier is converted to a diffraction limited, linearly polarized beam by a self-referencing two wave mixing process in an infrared sensitive photorefractive crystal (Rh : BaTiO3). Up to 11.6W singlemode output is achieved with a 78% multimode to singlemode photorefractive conversion efficiency.
