A dark pulse generation is demonstrated in a fiber laser configured with a 20 cm long HBEDF and multilayer Black Phosphorus as a gain medium and saturable absorber, respectively. Dark pulses fiber laser at 1.5 μm region was obtained when the pump power exceeds the threshold of 147 mW. Meanwhile, the...
