Abstract

The feasibility of constructing a compact, all-fiber, dissipative soliton resonance (DSR) mode-locked erbium–ytterbium double clad laser emitting 6.517 µJ pulses directly from the cavity is presented. The laser was built in a figure-8 configuration and mode-locked using a nonlinear optical loop mirror. A DSR regime of operation was enforced in the cavity by large net-anomalous dispersion (−21.431 ps2), obtained by incorporating 1 km of SMF28 fiber in the resonator. The laser operated at a 201 kHz repetition rate, with maximum average output power of 1.31 W at 7.2 W of pump power, yielding an impressive 20% slope efficiency.
