Discussion

Demonstration of a fiber laser producing 1860-nm pulses, optimizing pulse duration and mode-locking using a saturable absorber.

Stable ultrafast 1860-nm fiber laser pulses were achieved with a pulse duration of 360 fs and a repetition frequency of 51.5 MHz.
Using violet phosphorene as a saturable absorber, the mode-locking self-starting threshold was significantly reduced.
Optimization efforts led to an improved 306 fs pulse duration for 1894-nm mode-locked laser outputs with stable characteristics.
The work advances the understanding of nonlinear optical effects and enhances the applications of ultrafast laser sources.
