We have successfully realized the soliton pulse in a Erbium-doped fiber laser (EDFL) cavity, which was mode-locked by a Titanium Aluminum Carbide (Ti3AlC2) MAX phase based saturable absorber (SA). The SA was obtained by embedding the Ti3AlC2 compound into polyvinyl alcohol (PVA) in form of thin film. The prepared Ti3AlC2 film has a modulation depth of 2% and it was added into an EDFL cavity to generate a stable soliton pulse operating at 1559.7 nm wavelength. The mode-locking operation was successfully observed within a pump power range from 66.3 to 97.6 mW. It has maintained the repetition rate and pulse width at 1.8 MHz and 5.02 ps, respectively. When the pump power reached 97.6 mW, the maximum average output power, pulse energy and peak power were measured to be 8.34 mW, 4.46 nJ and 0.89 kW, respectively. These results unveil the potential of Ti3AlC2 MAX-phase material for implementation as practical and cost-effective SAs.
