Vanadium carbide (V2C), a member of the MXene family, promises numerous possibilities in ultrafast laser technology with substantial applications in various optical industries. In this work, MXene V2C was deposited onto a tapered fiber using the drop-casting technique and incorporated into a thulium/holmium doped fiber laser cavity for generating mode-locked outputs in the 2.0 µm region. The fabricated SA exhibited nonlinear optical properties such as saturation intensity and modulation depth of 2.07 MW/cm2 and 7.57%, respectively. The findings of the mode-locked characteristics showed a central wavelength of 1937 nm with a signal-to-noise ratio (SNR) of 73 dB. Correspondingly, the laser-generated mode-locked pulses with output power, pulse energy, and peak power of 2.71 mW, 235.2 pJ, and 0.14 kW, respectively. The results suggest that the mode-locked laser obtained based on the MXene V2C could be applied to the field of photonics.
