A cladding-pumping based power-scaled noise-like and dissipative soliton pulse fiber laser

Abstract

We report a high-average-power noise-like pulse (NLP) and dissipative soliton (DS) pulse fiber laser. Average power as high as 4.8 W could be obtained at the fundamental mode-locked repetition rate. The NLP can also be evolved into more powerful DS mode-locking state by optimizing the polarization and losses of intra-cavity pulses in nonlinear polarization evolution regime. The operation mode between NLP and DS can be switched, and the laser output performance in both modes have been studied respectively. The main advantage of this work is switchable high-power operation between NLP and DS. In comparison with conventional single-mode NLP fiber lasers, the multi-function high-power optical source will greatly push its application in supercontinuum generation, coherence tomography, and industrial processing.
