Abstract

The effect of processing atmosphere and corona polarity has been considered when using a dc-corona to electric field pole polymer films for second harmonic generation (SHG). Positive and negative polarity coronas were used to pole doped polystyrene and poly(methyl methacrylate) films in air, nitrogen, nitrous oxide, and carbon dioxide environments. A possible correlation between the magnitude of the initial SHG intensity and the ionic mobility and the corona-onset voltage for a given atmosphere is discussed.
