Abstract

Single crystals of Gd_1-xR_xCa₄O(BO₃)₃ (R³⁺ = Sc³⁺ or Lu³⁺) with large size and good quality have been grown by Czochralski method. By changing the compositional parameter x of Gd_1-xSc_xCa₄O(BO₃)₃ and Gd_1-xLu_xCa₄O(BO₃)₃ crystals, their optical birefringence can be controlled in order to achieve non critical phase matching (NCPM) in the ranges of 792-824nm along Y axis and 922-963nm 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 R³⁺ ions in the Gd₄Ca₄O(BO₃)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.
