Experimental and numerical study of the switching dynamics of Raman fiber lasers

We present an experimental and numerical survey of the switching behavior of cascaded Raman fiber lasers (RFLs). When these lasers are switched on, the output power shows a pulsing behavior where the pulse powers strongly exceed the steady-state output powers. The influence of the pump-laser and fiber properties of a RFL on this dynamical behavior is investigated both experimentally and numerically, where experiments and simulations showed good qualitative agreement.
