摘　　要：A high power double-clad ytterbium-doped large-mode-area photonic crystal fiber（LMA PCF）laser was demonstrated using a unique Fabry-Perot （F-P） continnous wave （CW） output power of 50 W at～L04μm with a slope efficiency of 76.3% is obtained, Single transverse mode operation is achieved without any thermal-optical problems, This laser has the potential for scaling to much higher output power.A high power double-clad ytterbium-doped large-mode-area photonic crystal fiber（LMA PCF）laser was demonstrated using a unique Fabry-Perot （F-P） continnous wave （CW） output power of 50 W at～L04μm with a slope efficiency of 76.3% is obtained, Single transverse mode operation is achieved without any thermal-optical problems, This laser has the potential for scaling to much higher output power.
