Abstract
Q-switched Yb-doped fiber lasers based on 2H-MoTe2 was demonstrated in this paper. The saturable absorber (SA) was a film mixed by 2H-MoTe2 and polyvinyl alcohol (PVA). The modulation depth of the SA was 21.4% and the saturable optical intensity was 10.3 GW/cm-2. When the 2H-MoTe2 film was inserted into the cavity, the Q-switched pulses were obtained. To the best of our knowledge, this is the first time to realize the generation of Q-switching in a Yb-doped fiber laser based on 2H-MoTe2-PVA film.
