Abstract
This letter demonstrates the application of MAX phase material as saturable absorber (SA) for mode-locking in Erbium-doped fiber laser (EDFL). Here, we use titanium silicon carbide (Ti3SiC2) compound to make thin film in polyvinyl alcohol host polymer. The fabricated composite film exhibits a saturable absorption of 51% and it produces mode-locked pulses at 1559 nm in an extended 106 m long EDFL's cavity. The EDFL generates ultrashort pulses with repetition frequency of 1.88 MHz and pulse width of 3.03 ps when the pump is adjusted within 123.7-181.1 mW. At 181.1 mW, the laser achieves the pulse energy of 6.0 nJ and the peak power of 2.0 kW. Overall, the Ti3SiC2 SA establishes a compact and straightforward approach for mode-locking.
