Passively Q-switched fiber laser utilizing molybdenum titanium aluminum carbide (Mo2Ti2AlC2) for pulsed laser generation

In this work, Molybdenum Titanium Aluminum Carbide (Mo2Ti2AlC2) was examined to function as a reliable saturable absorber (SA) for stable pulse generation in the 1563 nm wavelength. To create the Mo2Ti2AlC2-PVA film, Mo2Ti2AlC2 powder with > 200 nm particle size was dispersed into polyvinyl alcoh...
