Linear and nonlinear optical properties of 3-methyl-4-methoxy-4′-nitrostilbene single crystals

Single crystals of the new nonlinear optical material 3-methyl-4-methoxy-4′-nitrostilbene (MMONS) have been grown by a seeded solution growth technique and the linear and nonlinear optic and electro-optic properties determined. MMONS is highly birefringent with nz−nx =0.75 (0.532 μm), has large nonlinear optical coefficients with d33=184 pm/V and d24=71 pm/V (1.064 μm), has large electro-optic coefficients with r33=39.9 pm/V (0.6328 μm), and can be efficiently type II phase matched for Nd lasers emitting ∼1 μm.
