title: Dissipative shock waves in all-normal-dispersion mode-locked fiber lasers.
abstract: We propose an interpretation of the pronounced "M" spectral shape that is a recurrent feature in all-normal-dispersion mode-locked fiber laser dynamics. Our interpretation involves shock wave formation regularized by dissipation, modeled by a modified Burgers equation. The large fringes appearing at the edges of the spectrum result from discontinuities in the spectral phase.
