Summary:The phenomenon of pulse bunching was analyzed to study the stabilization of modelocking in fibre ring laser. The bunching characteristics of a stretched-pulse dispersion-managed ring laser were studied using equally spaced pulses in a simple ring cavity design. The laser output gave pedestal-free sech-profiled pulses bunched with regular spacing in 50 GHz range. It was observed that adjustment of wave plates created new pulses located far apart from the bunch. The autocorrelation results showed that the time position of the new pulse was unstable until it joined the equally spaced pulse train bunch.
