Crystal Growth, Structure Analysis, and Second-Order Nonlinear Optical Properties of 4-Cyanophenyl p-Anisate with Transparency in Visible Region

摘要

Single crystals of 4-cyanophenyl p-anisate (CPA), an organic nonlinear optical material, have been prepared. The crystal structure of CPA has been determined and found to belongs to the non-centrosymmetric space group P2_12_12_1. The second-order nonlinear optical coefficient (d) was estimated using the oriented gas model with the crystal structure, and the d_(14) of CPA was obtained to be 26pm/V.
