Summary: This study investigates the use of Molybdenum Titanium Aluminum Carbide (Mo2Ti2AlC2) as a reliable saturable absorber (SA) for stable pulse generation at a wavelength of 1563 nm. A Mo2Ti2AlC2-PVA film was created by dispersing Mo2Ti2AlC2 powder with > 200 nm particle size into polyvinyl alcohol (PVA) and drying it to form a film. The Mo2Ti2AlC2-PVA film exhibited a linear absorption coefficient of approximately 1.5 dB at the Q-switched working wavelength. Self-started Q-switching was achieved with pump power ranging from 20 mW to 55 mW, resulting in a pulse width reduction from 21.7 μs to 8.9 μs and an increase in repetition rate from 20.45 kHz to 40.40 kHz. The pulsed laser showed good stability, with a signal-to-noise ratio (SNR) of 61 dB. The highest output power and pulse energies were measured at 1.1 mW and 27.2 nJ, respectively. These findings highlight the potential of Mo2Ti2AlC2 as an alternative passive SA for laser pulsing at the 1.55-micron wavelength.
