Stable single-, dual-, and triple-wavelength DSs achieved

Multi-wavelength operation depends on cavity birefringence

Mechanisms of multi-wavelength DS formation discussed

Abstract

We report on the generation of multi-wavelength dissipative soliton (DS) in an all normal dispersion fiber laser passively mode-locked with a semiconductor saturable absorber mirror (SESAM). We show that depending on the strength of the cavity birefringence, stable single-, dual- and triple-wavelength DSs can be formed in the laser. The multi-wavelength soliton operation of the laser was experimentally investigated, and the formation mechanisms of the multi-wavelength DSs are discussed.
