Paper Abstract

Single crystals of Gd1-xRxCa4O(BO3)3 (R3+ = Sc3+ or Lu3+) with large size and good quality have been grown by Czochralski method. The optical birefringence of Gd1-xScxCa4O(BO3)3 and Gd1-xLuxCa4O(BO3)3 crystals can be controlled by changing the compositional parameter x. 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. According to our assumptions, the obtained results demonstrate that two of the grown crystals convert the near-infrared radiation of 800nm into blue-violet light (400nm) by type-I noncritical phase-matching (NCPM) second-harmonic generation (SHG) processes along Y axis.
