Research Progress in Chalcogenide Glass Raman Fiber Lasers

Abstract

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.
