Optical modulation of the MXene Ti3C2Tx saturable absorber for Er: Lu2O3 laser

In this paper, we successfully prepared MXene Ti3C2Tx nanosheets via diffusing method and subsequently investigated its nonlinear absorption properties. A diode-pumped passively Q-switched Er:Lu2O3 laser at 2.85-mu m was realized applying the MXene Ti3C2Tx as a saturable absorber (SA). Up to 1.13-W average output power was achieved under the pump power of 8.41 W. The pulse duration of the pulsed laser was 187.89 ns with repetition rate of 149.16 kHz and the pulse energy of 7.6 mu J.
