What is dark soliton fiber lasers?

In the non-mode locking regime,the first dark soliton fiber laser has been successfully achieved in an all-normal dispersion erbium-doped ﬁber laser with a polarizer in cavity. Experimentally finding that apart from the bright pulse emission, under appropriate conditions the ﬁber laser could also emit single or multiple dark pulses. Based on numerical simulations we interpret the dark pulse formation in the laser as a result of dark soliton shaping.
