| Popis: | Passive Q-switching of praseodymium (Pr3+)-doped fiber lasers at 635 nm with topological insulators (TIs) saturable absorbers (SAs) was experimentally demonstrated for the first time. TIs (Bi2Se3, Bi2Te3) nanosheets were embedded in polyvinyl alcohol for film-forming and incorporated into a visible Pr3+-doped fiber laser cavity for Q-switching operation, respectively. The Bi2Se3-based Q-switched fiber laser has a wide range pulse-repetition-rate from 191.6 to 454.5 kHz, and the Bi2Te3 one can be continuously tuned from 164.5 to 403.2 kHz. Both the Q-switching lasers have narrow pulse duration of nanosecond (ns)-level. Our results reveal that the TIs-based SAs are available for pulsed operation in the visible spectral range. |
