Linear and second-order nonlinear optical (NLO) properties of a single crystal of N-benzyl-2-methyl-4-nitroaniline (BNA) have been determined. The refractive indices of the crystal were measured in the visible to near infra-red region. The Maker-fringe and phase-matching methods were used to determine the magnitudes of the d-tensor components for the second harmonic generation when excited the crystals at 1064 nm. They were d333 = 234 ± 31, d322 = 15.6 ± 0.9, and d311 ∼ 0 pm/V. The value of d333 is the largest value reported for any yellow-colored NLP materials and suggests that crystals of BNA will be very effective for terahertz wave generation.
