英文摘要	In this work, a Yb3+/Al3+/P5+/F- co-doped low-NA preform with larger than 0.4 wt.% Yb3+ doping concentration and zigzag refractive index profile was fabricated based on solution doping modified chemical vapor deposition technology. The modality of the preform refractive index profile was simulated based on a circle-symmetry-distribution fiber model. According to the simulation results a step-index 25/400 double cladding fiber with core NA of similar to 0.04 was drawn. Pumped with a 970 nm laser diode, a diffraction-limited oscillator-laser output with similar to 71% slope efficiency and M-2 of similar to 1.06 were achieved at bending diameter. 50 cm after stripping cladding light. For bending diameters less than 50 cm, the laser efficiency measured at stripping cladding light decreases with decrease in bending diameter.
