The focus of this study was the development of a second generation offiber lasers internally cooled by anti-Stokes fluorescence. The laserconsisted of a length of a single-mode fiber spliced to fiber Bragggratings to form the optical resonator. The fiber was single-moded atthe pump (1040 nm) and signal (1064 nm) wavelengths. Its core washeavily doped with Yb, in the initial form of CaF2nanoparticles, and co-doped with Al to reduce quenching and improvethe cooling efficiency.
