In this work, a WTe2 coated tapered fiber was used as a saturable absorber (SA) to induce mode locking in a thulium/holmium doped fiber (THDF) laser through evanescent field interaction. The WTe2 was drop-casted onto the tapered fiber to form an SA which had a modulation depth of 18.08%, saturation...
