Semiconducting Polymer Dots as Saturable Absorbers for Mode-Locked Thulium-Doped Fiber Lasers

Semiconducting Polymer Dots as Saturable Absorbers for Mode-Locked Thulium-Doped Fiber Lasers

We demonstrated an all-fiber passively mode-locked thulium-doped fiber laser (TDFL) using organic semiconducting polymer dots (Pdots) based saturable absorber (SA). The Pdots are prepared by methods of donor-acceptor moieties and reprecipitation, which possess a broadband absorption from 400 to 2200...
