Abstract

We have proposed a MOPA configuration with a stepwise optical frequency pulse train (SOFPT) seed in which the SBS threshold does not decrease even if the duty-cycle of the pulse train is increased up to ~100%. In this paper we present the SBS thresholds of a passive fiber in range of 45ns-500ns pulse duration under the low-duty-cycle condition. Based on the experimental results and theoretical consideration, we estimated the achievable average power of > 8 kW in a MOPA configuration with the SOFPT, in which each pulse has a sub-GHz linewidth.
