Abstract

Nonlinear optical borate crystals of Gd1-x-yRxNdyCa4O(BO3)3 crystals with large size and good quality have been grown from the melt by the Czochralski pulling method. The chemical compositions of the grown crystals were determined and nonlinear optical properties of these new biaxial crystals are reported. According to our assumptions, the obtained results demonstrate that the grown crystals convert the near infrared radiation of ~ 936 nm into blue light (~ 468 nm) by type-I noncritical phase matching (NCPM) second harmonic generation (SHG) processes along Z axis. Preliminary investigations of self frequency doubling (SFD) processes in Gd1-x-yRxNdyCa4O(BO3)3 crystals have been carried out.
