    Growth and characterization of LiYF4:Er+3 fibers
    2008 - SILVA, F.R.; MIRAGE, A.; SANTO, A.M.E.; MARTIN, A.A.; BALDOCHI, S.L.
    The growth of single crystal fibers of LiYF4 (YLF) doped with Er3+ was studied through the resistive micro-pulling-down (µ-PD) technique. The growth chamber was modified to achieve vacuum of approximately 10-7torr. Single crystal fibers of YLF: Er (1, 10 and 20 mol %), with 0.7 mm of diameter and up to 120mm of length were grown. The use of a static atmosphere was found to be inappropriate for elimination of spurious contamination from growth environment for this experimental setup.
