Abstract:
We numerically study a stable multiple-pulse operation of passively modelocked stretched pulse fiber ring laser. The simulation results show that multiple pulses are formed with being triggered by radiation from a single pulse in a restricted parameter range. In order to obtain a better understanding of the effect of gain bandwidth and nonlinear gain on harmonic modelocking process of multiple-pulse operation, we analyze those effects in detail.
