Abstract
We report a Q-switched Er3+:ZBLAN fiber laser based on Vanadium Aluminum carbide (V4AlC3) as a saturable absorber (SA). Our SA is fabricated by depositing V4AlC3 nanoparticles on a gold mirror to form an SA film. The proposed laser operates at the 2784.32 nm central wavelength with a 1.68 nm 3 dB bandwidth. The maximum pulse energy and output power are 3.51 µJ and 490 mW at a maximum pump power of 6.6 W. To the best of our knowledge, this is the first time that V4AlC3 provides Q-switching in the 3 µm region. The proposed SA is promising for mid-infrared pulsed lasers.
