摘　　要：An Yb3+-doped double-clad large-mode-area photonic crystal fiber(LMA PCF) laser with up to 210 W of continuous-wave output power centered at 1.05 μm is demonstrated.The length of the fiber used is 2 m and the produced laser power per meter can attain 105 W.The PCF is pumped by two diode lasers with central wavelength of 976 nm.The slope efficiency is 76%,and the beam quality factor M2 at x and y axes are measured to be 1.06 and 1.08,respectively.No thermo-optical problems and other roll-over even are observed at the highest output power.An Yb^3＋-doped double-clad large-mode-area photonic crystal fiber （LMA PCF） laser with up to 210 W of continuous-wave output power centered at 1.05 lira is demonstrated. The length of the fiber used is 2 m and the produced laser power per meter can attain 105 W. The PCF is pumped by two diode lasers with central wavelength of 976 nm. The slope efficiency is 76%, and the beam quality factor M^2 at x and y axes are measured to be 1.06 and 1.08, respectively. No thermo-optical problems and other roll-over even are observed at the highest output power.
