Chalcogenide glasses have many attractive characteristics including wide infrared transmittance, extremely high linear and nonlinear refractive indexes. Recently, stimulated Raman effects in chalcogenide glass fibers attract extensive attention for their potential applications in all-optical devices and cascade lasers. In this article, the research progress in chalcogenide glass Raman fiber lasers (RFLs) is reviewed, including cascaded chalcogenide RFL, mi• crowire chalcogenide RFL, and theoretical studies of chalcogenide RFL. Current challenges in RFL are discussed their potential applications are summarized.
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.
