Ti₂AlC is a kind of ternary layered structured ceramic metal compound, combing advantages of both ceramic and metal. Herein, the saturable absorption performance of Ti₂AlC at 1 μm waveband is investigated for the first time. The Ti₂AlC behaves with excellent saturable absorption, which has a modulation depth of 14.53% and a saturable intensity of 13.27 MW/cm². An all-normal dispersion fiber laser based on the Ti₂AlC saturable absorber (SA) is constructed. The repetition frequency of the...
