Abstract

We demonstrate the first stable mode-locking from an Er³⁺ doped fluoride fibre laser cavity using various novel two-dimensional saturable absorber materials such as PtSe₂ and MXene operating near 2.8 μm wavelength to the best of our knowledge. The linear cavity includes a high reflective chirped fibre Bragg grating to provide wavelength stability. The observed mode-locked pulse train has a 30 MHz repetition rate and an average power of 223 mW. Our results demonstrate the feasibility of using the novel two-dimensional nanomaterials such as PtSe₂ and MXene into the fibre laser cavity for the application in mid-infrared wavelength regime.
