Abstract:The oscillation of erbium doped fiber lasers (EDFL) in the Q-switch mode is investigated. Etched out fiber tapers coated with two types of saturable absorbers (SA) are tested as passive Q-switches. SA of the first type comprises two-component silicone with nano-flakes of a Bi 2 Te 3 single crystal dissolved in it. A thin film of Bi 2 Te 3 synthesized by the Metalorganic Chemical Vapor Deposition (MOCVD) method on the surface of the fiber taper and coated with the same silicone served as SA of the second type. … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
