We present a detailed analysis of second-harmonic-generation Maker fringes in biaxially birefringent materials that takes into account the ordinary as well as the extraordinary polarized bound and free waves. This becomes relevant for elliptically polarized second-harmonic-generation signals. To keep the formulas easy to survey, the calculation is performed in a compact 4×4 matrix technique. For a test of the analysis we apply it to measurements in birefringent single crystals of the asymmetrically substituted diacetylene NP/4-MPU.
