A New Intramolecular Charge Transfer Material for Nonlinear Optics: Piperonal Derivatives

Abstract

ABSTRACTThis paper describes a new organic nonlinear material, piperoniridene ethyl cyano acetate which shows short cut-off wavelength, good nonlinearity (better than POM in powder) and good crystallinity. These features of this compound encourage its application in second harmonic generation (SHG) coupled with semiconductor laser.
