Abstract
In this paper, a new thin-film saturable absorber (SA) that belongs to the MXene family is used to generate Q-switched laser pulses. In constructing the SA, titanium carbide (Ti3C2Tx) powder obtained through a selective etching process is dispersed in polyvinyl alcohol solution before the mixture is dried to form a thin film. A small piece of the film is placed between two fiber ferrules to form a SA device and added to a laser cavity of an erbium-doped fiber laser to produce Q-switched pulses in the region of 1561 nm. The repetition rate of the pulses can be varied between 45.25 and 65.59 kHz with the corresponding pulse width of 5.04-3.11 mu s when the pump power is increased from 29.8 to 66.3 mW. At the maximum output power of 8.17 mW, the highest pulse energy of 125 nJ is obtained.
