abstract |
Gadolinium oxyorthosilicate single crystals (Gd-2(SiO4)O (GSO)) were obtained by the laser floating zone (LFZ) technique. The fibres were pulled at faster growth rates (10 mm/h) than those produced by the conventional Czochralski method and the growth was performed in air, which did not require environmental control. The structural characterization of as-grown fibres made by X-ray diffraction (XRD) and Raman spectroscopy puts in evidence the high degree of crystallinity and its monoclinic nature. The optical characterization, accomplished by photoluminescence and photoluminescence excitation, suggests that GSO fibres are a promising candidate to be doped in order to develop new high optical efficient laser materials.
