Photosensitivity and Photodarkening of UV-induced Phosphate Glass Fiber Bragg Gratings and Application in Short Fiber Lasers
… integration of UV-written intra-core fiber Bragg gratings (FBGs) into the fiber laser cavity. The research presented in this thesis is focused on the investigation of photosensitivity of UV-written Bragg gratings in phosphate glass fibers and their application in direct-written short monolithic …
