Abstract
Microstructure fibers (MSFs) are attractive for applications in fiber lasers and many other devices for optical communication. This paper deals with the preparation and characterization of MSFs with cores doped with ytterbium and erbium ions. The fibers were drawn from preforms consisting of a stack from a central rod and silica capillaries inserted in a silica tube. Rods whose central parts were doped with rare-earth ions were used. These rods were prepared by the MCVD method combined with liquid-phase etching. The fibers were characterized by optical microscopy and by measurement of their spectral attenuation. They were also tested in experimental amplifier and laser set-ups. The fibers were excited at 1060 nm and saturated gains of about 26 dB, or laser power conversion efficiency at a wavelength range around 1550 nm were measured. These measurements show results comparable with conventional fibers doped in the core with ytterbium and erbium ions.
