摘要：

The Nb2AlC material has attracted more and more attention in optoelectronics due to its excellent optical properties. Herein, the Nb2AlC-based saturated absorber (SA) was fabricated by ultrasonic thermal dissolution method and spin coating means, and a passively mode-locked (PML) Tm:YLF laser was perfectly demonstrated with the SA. With an incident pump power of 21.63 W, a 0.379-W average output power and a 200-ps pulse width were achieved at 1872.1 nm, corresponding to a per pulse energy of 3.15 nJ and a peak power of 15.75 W. In addition, the beam quality factors were measured to be 1.04 and 1.05 in the horizontal direction and vertical direction.
