Abstract
We have demonstrated dual-wavelength domain-wall (DW) dark pulse operation based on Molybdenum disulfide (MoS2). MoS2 is fabricated as a film and sandwiched between two pigtails to function as a saturable absorber in the laser cavity. The DW dark pulse exhibited two peaks, which are located at 1037 and 1039 nm. The pulse repetition rate was maintained at 17.4 MHz throughout the DW dark pulse operation. The highest pulse energy of 46 pJ was obtained at pump power of 242.5 mW. Besides, DW dark pulse operation was demonstrated at high stability with SNR of 50 dB.
