The laser heated pedestal growth technique was used to obtain single crystal fiber of M-type GdTaO4. The fibers were around 3 cm long, +0.8 mm, 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 (0 1 0) direction presenting rocking curve FWHM typically around 52 arcsec for the ð3 ¯23Þ reflection.The results confirm that good structural fibers can be successfully obtained by the procedure presented here.
