摘要：

Pure and Nd3+ doped single crystals of Gd1-xRxCa4O(BO3)(3) (R3+ = Sc3+ or Lu3+) with large size and good quality have been grown by the Czochralski pulling technique. By changing the compositional parameter x of Gd1-xRxCa4O(BO3)(3) crystals, their optical birefringence can be controlled in order to achieve non-critical phase matching (NCPM) in the ranges of 790-824 nm along Y-axis and 920963 nm along Z-axis, during second harmonic generations. Nonlinear optical properties of these new biaxial borate crystals are reported. Preliminary investigations of self frequency doubling in NCPM condition in Gd1-x-yRxNdyCa4O(BO3)(3) crystals have been carried out. (c) 2006 Elsevier B.V. All rights reserved.
