Fabrication of Fiber Bragg Gratings by Visible Femtosecond Laser for Multi-kW Fiber Oscillator

In this paper, we fabricate a pair of fiber Bragg gratings (FBGs) in large mode area double cladding fiber (LMA-DCF, core/inner cladding diameter: 20/400 μm) by visible (515 nm) femtosecond laser and phase mask for the first time to the best of our knowledge. Then this pair of F...
