Abstract

We report a new organic nonlinear optical crystal, 2, 6-dibromo-N-methyl-4-nitroaniline (DBNMNA). The refractive indices of DBNMNA were measured at several wavelengths between 500 and 1100 in and fit to a single oscillator Sellmeier equation. Second harmonic Maker fringe data yielded d33 values through comparison with y-cut crystalline quartz. We also report measurements of the electro-optic coefficients, (na3r13-nc3r33) r42, and r51 at several wavelengths. We find good agreement between the observed dispersion and that predicted by the simple two level dispersion model. However, the second order susceptibility is not well described by a single tensor component hyperpolarizability.
