摘要

Single crystals of Gd_(1-x)R_xCa_4O(BO_3)_3 (R~(3+) = Sc~(3+) or Lu~(3+)) with large size and good quality have been grown by Czochralski method. By changing the compositional parameter x of Gd_(1-x)Sc_xCa_4O(BO_3)_3 and Gd_(1-x)Lu_xCa_4O(BO_3)_3 crystals, their optical birefringence can be controlled in order to achieve non critical phase matching (NCPM) in the ranges of 792 - 824 nm along Y axis and 922 - 963 nm along Z axis, during second harmonic generations (SHG). The chemical compositions of the grown crystals were determined and X-ray diffraction measurements have been carried out to characterize the structural changes with compositional parameter x. The solubility limits of R~(3+) ions in the Gd_4Ca_4O(BO_3)_3 crystals were also determined. Nonlinear optical properties of these new biaxial borate crystals are reported. Experimental determinations of doubled frequencies in NCPM conditions are in good agreement with theoretical predictions.
