Abstract
We report the inscription of fiber Bragg gratings (FBGs) into a nonphotosensitive Er-doped fiber by using a phase-mask scanning technique with near IR femtosecond laser pulses. A grating of length with a period of was realized. We measured transmission losses of at with a FWHM bandwidth of . By pumping the fiber containing the fabricated FBG, it was possible to realize a fiber laser with an output power of , a slope efficiency of 21.1%, and low noise .
