Effective nonlinearity of trigonal BaGa<sub>2</sub>GeS<sub>6</sub>
Implementing second-harmonic and sum-frequency generation processes with a specially oriented sample, we determine the magnitude and sign of the nonlinear optical coefficients d 11 , d 22 , and d 31 of the recently developed trigonal BaGa 2 GeS 6 . We conclude that it is a viable alternative to the widely used chalcopyrite AgGaS 2 for 1 µm pumped frequency downconversion to the mid-IR spectral range.
