摘要:
We proposed and demonstrated a technique to increase the pulse energy output in a single-mode all normal dispersion (ANDi) passively mode-locked fiber laser, which is based on nonlinearity optimization within the cavity together with a high output coupling ratio. With an output ratio of 95%, an average power of 460 mW at a repetition rate of 1.3 MHz is achieved, corresponding to a single-pulse energy of 354 nJ. To the best of our knowledge, the result is the highest energy with high average power output for ANDi passively mode-locked fiber lasers based on single-mode fibers. (C) 2015 Elsevier B.V.
