摘要：Crystal materials with integrated functionalities are desirable for the miniaturization of future optical devices. In this paper, nonlinear optical crystals of Ca3TaGa3Si2O14 (CTGS) and Nd3+ doped CTGS (Nd:CTGS) were grown using the Czochralski pulling method and explored for self-frequency-doubling applications. Based on the refractive indexes, the optimum phase matching directions for CTGS crystals were determined for type I (38.7 degrees, 30.0 degrees) and type II (61.1 degrees, 0 degrees) orientations, with respective effective nonlinear optical coefficients on the order of 0.44 pm V-1 and 0.34 pm V-1. Self-frequency-doubling was realized in Nd:CTGS crystals [(38.7 degrees, 30.0 degrees) (type I)] for the first time, and 18.8 mW laser power at 533 nm was achieved.
