A solid-state passively Q-switched Tm,Gd:CaF2 laser with a Ti3C2T x MXene absorber near 2 µm
Abstract
Ti3C2Tx, a novel two-dimensional material in the MXene family, was successfully prepared and applied as a saturable absorber (SA) for solid-state pulsed lasers at 2 µm. Pumped by a 792 nm fiber-coupled laser diode, a compact passively Q-switched Tm,Gd:CaF2 laser with a Ti3C2Tx-SA was demonstrated and the pulse laser performances were presented and discussed in detail. This is the first presentation of Ti3C2Tx as a SA for solid-state pulsed laser generation near 2 µm.
