Abstract
This paper presents experiments that show the buildup of noise-like pulses in an ultrafast fiber laser, with real-time spectral characterization. By changing the dispersion regime, markedly different physical mechanisms are highlighted. Besides their diversity, these paradoxical chaotic dynamics combining instability and localization illustrate the recent concept of incoherent dissipative solitons.
