We experimentally demonstrate the use of a bulk-structured Bi2Te3 topological insulator (TI) deposited on a side-polished fiber as an effective saturable absorber for the implementation of an all-fiberized passively Q-switched 1.06 μm fiber laser. Unlike previous Q-switched laser demonstrations based on nanosheet-based TIs, which require complicated and sophisticated fabrication procedures, a ~9.1 μm-thick bulk-structured Bi2Te3 TI film that was prepared using a mechanical exfoliation method… CONTINUE READING
