Abstract
We present a comparative study of the linear and nonlinear optical properti es of two isomorphous organic-inorganic crystals: the 2-amino-5-nitropyridi nium-dihydrogenphosphate (2A5NPDP) and -dihydrogenarsenate (2A5NPDAs). We d etermine accurate equations for the dispersion in wavelength of their princ ipal refractive indices from direct prism measurements and from angular non critically phase-matched second-harmonic generation (SHG) experiments. We d educe the quadratic nonlinear coefficients d(15) and d(24) of each compound from the phase-matched conversion efficiency of SHG experiments and find t hat they are close to those of KTiOPO4.
