Lasing mode control of fiber lasers by higher-order fiber grating
By inscribing a refractive index structure directly into the core with a femtosecond laser, forming a long period fiber Bragg grating, we were able to control the oscillation of a narrow linewidth fiber laser, which was not possible with conventional quarter-wave Bragg gratings.
