摘要：

The laser heated pedestal growth technique was used to obtain single crystal fiber of M-type GdTaO4. The fibers were around 3cm long, phi0.8mm, transparent, colorless and did not exhibit any inclusions. The structural quality of the fibers was evaluated by X-ray rocking curve profiles and X-ray topography. Better quality crystals were grown perpendicular to (010) direction presenting rocking curve FWHM typically around 52 arcsec for the (353) reflection. The results confirm that good structural fibers can be successfully obtained by the procedure presented here. (C) 2004 Elsevier B.V. All rights reserved.
