High external power narrow bandwidth erbium doped waveguide laser on thin film lithium niobate [PDF]
NanophotonicsErbium-doped waveguide lasers have attracted great interests in recent years due to their compact footprint, high scalability and low phase noise. In this work, by using a high-external-gain erbium-doped thin-film lithium niobate waveguide as the gain ...

Two chaotic synchronizations in er-doped fiber lasers and their application in two-channel coding secure communications [PDF]
ITM Web of Conferences, 2022 A dual-ring erbium-doped fiber laser has nonlinear dynamic characteristics based on optical coupling interaction of lasing from the two laser rings and can send chaotic lasing to encode and mask an information to perform secure communication.

Erbium doped random fiber laser and fiber mixing effect [PDF]
2017 19th International Conference on Transparent Optical Networks (ICTON), 2017 We demonstrate an active random fiber laser by directly pumping a 100 m erbium-doped fiber at 980 nm wavelength, with a fiber loop mirror forming a half-open cavity. Random lasing with competing spectral modes in the range from 1535 nm to 1560 nm is achieved, with the maximum lasing slope efficiency around 10%.
