Abstract
In this work, a V2AlC-based saturable absorber (SA) was applied to a 2 μm band passively mode-locked (PML) laser. The saturation intensity and modulation depth of the V2AlC-based SA were detected by the I-scan method, which were 225.05 MW/cm2 and 7.68%, respectively. In the PML mode, an average power of 2.12 W at 1939 nm and a pulse width of 1077 ps at 82.49 MHz were obtained from the Tm:YAP laser. In addition, the laser exhibited a good beam quality factor (M2) which was measured to be less than 1.2. These results will pave the way for the application of V2AlC-based SA in ultrafast lasers.
