ABSTRACT
Some novel solution saturable absorber (SA) such as black phosphrous (BP), WS2 and MoS2 are fabricated by liquid-phase-exfoliated method and used for passively Q-switched Nd:YVO4 laser successfully. Compared with traditional solid SA, solution SA possesses more excellent optical transparency and higher damage threshold. The shortest pulse duration are measured to be 3 ns. Similar solution absorbers are used in mode locking of fiber lasers. The SA is fabricated based on a D-shaped fiber (DF) embedded in Wide band material solution. Such absorbers have virtues of good antioxidant capacity, excellent scattering resistance, high heat dissipation and high damage threshold. Femtosecond laser pulses and picoseconds laser pulses are obtained in Er doped fiber lasers and Yb doped fiber lasers.
