PURPOSE: To obtain nonlinear optical material having short absorption edge and large nonlinear optical characteristic by using a specific organic compound. CONSTITUTION: The organic compound shown in the formula I, peclon (N- nitrophenyl hydroxylamine ammonium salt) is used. Because this organic compound has short π-conjugate length, the absorption edge is short and there is little fear to absorb output higher harmonics, and because the construction is of intermolecular salt, the crystallizing condition is stable and the crystal is easily made. Hereby, nonlinear optical material having large nonlinear optical characteristic and short absorption edge can be obtained. COPYRIGHT: (C)1992,JPO&Japio
