    Nanocrystalline ZrO2-doped active optical fibers for fiber lasers operating at 2 mu m

  • Original language description

    In this work, phase-separated fibers of the system SiO2-ZrO2 doped by thulium and holmium ions were prepared by modified solution-doping method combined with MCVD. The ZrO2 concentration in both fibers was approx. 3 mol. %. The rare-earth ion concentrations were 270 and 740 ppm, respectively. The presence of ZrO2-based nanoparticles in the optical fiber preforms was confirmed by scanning electron microscope (SEM). The background losses of the fibers were in the range of 0.1 - 0.6 dB/m. The fibers exhibited strong emission in the near-infrared region thanks to 4f-4f transitions of rare-earth ions. The photoluminescence decay of both fibers exhibited double exponential character, most likely due to the incorporation of rare-earth ions in different optically active sites, i.e. ZrO2-based nanoparticles and grain boundaries or amorphous silica matrix. The fibers were tested as active mediums in fiber laser setup. The thulium-doped fiber exhibited threshold for laser operation of 233 mW and slope efficiency of 72.7 %. The holmium doped fiber failed to manifest lasing properties. An improved laser performance may be achieved by higher proportion of rare-earth ions incorporating in the favorable environment of the nanoparticles
