In this letter,a titanium aluminum carbide(Ti3AlC2)coated D-shaped fiber is proposed and demonstrated as a new saturable absorber(SA)for Q-switched laser pulse generation.In preparing the SA,the Ti3AlC2 powder is dispersed in liquid polyvinyl alcohol(PVA)before the solution is dropped and left to dry onto a polished surface of D-shape fiber.The SA is added to an erbium-doped fiber laser(EDFL)cavity to modulate the cavity loss for Q-switching.The Q-switched laser is obtained at 1 561 nm.The pulse width of the pulses can be varied between 7.4 μs and 5.1 μs with a corresponding repetition rate range from 41.26 kHz to 54.35 kHz,when the pump power is increased from 42.2 mW to 71.5 mW.At 71.5 mW pump,the pulse energy is obtained at 70.3 nJ.The signal-to-noise ratio(SNR)of the funda-mental frequency is recorded at 67 dB,which indicates the stability of the laser.
