Abstract

A dark pulse multi-wavelength mode-locked fibre laser was demonstrated via the enhanced zirconia-yttria-aluminium co-doped silica fibre (Zr-EDF) as a gain medium with the utilisation of black phosphorus as saturable absorber (BPSA). A self-started dark pulse was accomplished by increasing the pump power and carefully rotating a polarisation controller (PC). Five lasing lines of multi-wavelength were generated with small constant channel spacing of 0.6 nm. The measured fundamental repetition rate was 1 MHz with a pulse duration of 3.46 ps. At output power 9.89 mW, the calculated pulse energy was 9.89 nJ, whereas the optical signal to noise ratio (OSNR) was as high as 74.8 dB, which confirmed the stability of the dark pulse train.
