A cladding-pumped fiber laser with pump-reflecting inner-cladding Bragg grating
A fiber Bragg grating (FBG) was inscribed in the inner cladding of a double-clad fiber, in order to reflect, and thus, double-pass, the pump radiation in a cladding-pumped fiber laser. The effective pump reflectivity of the inner-cladding FBG was ~46.4%. This increased the slope efficiency of a Yb-d...
