Second-order nonlinear optical coefficients of the monoclinic crystal BaGa 4 Se 7

We characterize the magnitude and relative signs of the second-order nonlinear optical coefficients of the biaxial crystal BaGa Se (BGSe) combining measurements of phase-matched and non-phase-matched second-harmonic generation at different wavelengths using slabs and a sphere.
