MXenes have been demonstrated as saturable absorbers for mode-locking in fiber laser systems operating from 1 to 2 mu m wavelength. Despite that, there has been no utilization of MXene as a mode-locker at the extended 2 mu m wavelength. In this work, we present the potential of MXene material (Cr2C) for mode-locking in a Holmiumdoped fiber laser (HDFL). The Cr2C-SA had a saturation intensity of 1.7 MW/cm2 and a modulation depth of 14.2 %, respectively. Stable fundamental mode-locked pulses were realized at the pump power of 1.6 W. The mode-locked pulses had a repetition rate of 13.74 MHz, centered at 2077.54 nm, with a pulse duration of 1.75 ps. This study presented the first HDFL system to use MXene as a saturable absorber and the first utilization of Cr2C as a mode-locker.
