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.
We demonstrated the noise-like pulse (NLP) generation in an erbium (Er) doped fiber laser at 1560 nm based on 2HMoTe2. The saturable absorber (SA) was a film mixed by 2H-MoTe2 and polyvinyl alcohol (PVA). The moudulation depth of the SA was 21.4% and the saturable optical intensity was 10.3 GW/cm2. When the 2H-MoTe2 film was inserted into the cavity, the stable NLPs with 3-dB spectral bandwidth of 2.44 nm and the repetition rate of 33.7 MHz were obtained. The autocorrelation (AC) trace of NLP has a 1.14 ps spike and a 71 ps pedestal. When the pump power was 600 mW, the maximum output power was 26.09 mW. To the best of our knowledge, this is the first time to realize the generation of NLP mode locking in an Er-doped fiber laser based on 2H-MoTe2-PVA film.
