Pure and neodymium-doped gadolinium calcium oxoborate crystals of high quality were grown by the Czochralski method.The orientation of crystal was precisely det
YbxY1-xAl3(BO3)4(x=0.1,0.07 and 0)crystals have been grown by the flux method.The growth defects of YbxY1-xAl3(BO3)4 crystals were detected by X-ray topography.
