## Abstract An actively modeโlocked fiber laser (AMLFL) based on the hybrid gain of a dispersionโshifted fiber (as the Raman gain medium) and an Erbiumโdoped fiber (EDF) is introduced. The fiber Raman gain mechanism can effectively suppress the gain competition of an EDF, which usually results into
In this paper, a multiwavelength erbium-doped fiber laser based on a microstructure fiber Bragg grating (FBG) is proposed and demonstrated. The fiber Bragg grating is fabricated in a large-air-hole microstructure optical fiber using the phase-mask method. The laser based on this novel grating can be
## Abstract The erbiumโdoped fiber ring laser (EDFL) exhibits a wavelength shift that results from the variation of its intracavity parameters, namely, the outputโcoupler reflectivity (R), active fiber length (L), and optical losses (ฮฑ) in the resonant cavity. A simple and fast technique for predic
