Nonlinear Optical Properties of a novel organic crystal: 2-Furyl Methacrylic Anhydride (FMA)

Abstract

We report a new organic nonlinear optical crystal, 2-Furyl Methacrylic Anhydride (FMA). Fig.1 shows the molecular structure of FMA. The crystal, whose cut-off wavelength is located at about 380nm, is almost transparent in visible region. The refractive indices were measured by employing Brewster angle method. One of second harmonic generation (SHG) coefficients, d33, was determined by Maker fringe method.
