1.9 mu m mode-locked fiber laser based on evanescent field interaction with metallic vanadium diselenide (VSe2)

A stable passively mode-locked Thulium/Holmium-doped fiber laser (THDFL) was demonstrated by depositing layers of vanadium diselenide (VSe2) onto a D-shaped fiber using the drop-casting method. The VSe2-coated D-shaped fiber was then incorporated into the ring cavity as a saturable absorber (SA). Th...
