A new type of chalcone crystal was prepared. Anisotropic indices with wavelength dispersion were measured by the Brewster angle method. The two largest second-harmonic generation (SHG) tensor components were determined by the wedge method and compared with d11 of 2-methyl-4-nitroaniline. Calculated collinear and noncollinear phase-matched SHG patterns reasonably fit the observed photographs.
