摘要：

A homemade double-tapered Yb-doped fiber is employed in a high-power narrow-linewidth fiber amplifier to improve the thresholds of nonlinear effects and transverse mode instability (TMI) effect. A bidirectional pumping configuration is employed, and a phase-modulated single-frequency fiber laser serves as the seed laser. As a result, an output power of 3630 W with 0.21 nm linewidth (stimulate Brillouin scattering limited) and an output power of 4180 W with 0.59 nm linewidth (TMI limited) are realized, corresponding to the slope efficiency of similar to 77%. The beam quality at the maximum output power is M-x(2)= 1.57, M-y(2) = 1.39. The results could provide a well reference for the power scaling of narrow-linewidth Yb-doped fiber amplifier.
