Titanium Disulfide Based Saturable Absorber for Generating Passively Mode-Locked and Q-Switched Ultra-Fast Fiber Lasers.

In our work, passively mode-locked and Q-switched Er-doped fiber lasers (EDFLs) based on titanium disulfide (TiS) as a saturable absorber (SA) were generated successfully. Stable mode-locked pulses centred at 1531.69 nm with the minimum pulse width of 2.

ZrSe nanosheet as saturable absorber for soliton operations within an Er-doped passive mode-locked fiber laser.

Two-dimensional materials have extensively promoted the development of ultrafast photonics in the past decade. In our work, the saturable absorption properties of were presented. The saturation intensity, modulation depth, and nonlinear absorption coefficient of the saturable absorber (SA) are about 13.
