•The Nd:CTGS was found to be a positive uniaxial crystal.•The PM directions were found to be type I(38.9°, 30°) and type II(61.7°, 0°).•The SFD was realized on the designed type I and type II Nd:CTGS crystal cuts.•The fabricated Nd:CTGS lasers possess low output threshold and high stability.
The self-frequency-doubling (SFD) lasers in visible region are of importance for optical applications. In this work, SFD green laser was realized on newly designed nonlinear optical crystal Nd doped Ca3TaGa3Si2O14 (Nd:CTGS). By optimizing the configurations, measuring the refractive indexes and coating the surfaces of Nd:CTGS crystal samples, the SFD green laser output at 533 nm was observed, and the maximum output power for type I (38.7°, 30.0°) crystal cut was obtained and found to be on the order of 71.58 mW. Meanwhile, the Nd:CTGS type I (38.7°, 30.0°) crystal cut was found to show low output threshold, being on the order of 0.52 W. The output power stability within 30 mins was observed to be better than 1%.
