We have realized a set of multimode lasers based on a double-clad Yb-doped fiber and Bragg gratings written on a graded-index multimode fiber. Efficient laser operation in the spectral range of 1.03-1.09 ฮผm has been observed. Spectral characteristics of the laser emission have been investigated.
A double-clad erbium/ytterbium-doped fiber laser (EYDFL) is demonstrated using a fiber Bragg grating (FBG) as wavelength selective filter in a linear cavity resonator. The effect of the FBG's wavelength on the performance of the EYDFL is also investigated. The slope efficiencies of the EYDFL are obt
A new method for fabricating double fiber Bragg gratings at the same location on a fiber is described. Two series of refractive index change in a fiber, not similar to the normal fiber grating, have been realized by a Fresnel prism interferometer. As a result, the transmission spectrum of the fiber
