Abstract
The effect of poling atmosphere and voltage polarity on the second harmonic generation (SHG) and surface voltage of corona poled doped polymer films has been investigated. Poling is used to orient the guest nonlinear optical (NLO) dopants into the noncentrosymmetric orientation required to observe SHG signal. Poly(methyl methacrylate) films doped with disperse orange 3, an NLO dye, were poled with positive and negative polarity corona discharges in humid and dry air, helium and nitrogen atmospheres. The effect of the poling polarity and the atmosphere on the temporal stability of the second harmonic signal is discussed.
