Voltage thresholdlike evidence during thermal-electric field induction of second order nonlinearity in soda-lime glasses

Thermal-electric field poling of soda-lime glasses with modulated applied voltage based on the peculiar dependence of the electroluminescence activation energy is investigated. The second order nonlinearity (SON) stability upon infrared laser pump has show an abrupt change for poling voltage of ∼900V. The contributions to the onset of the SON are treated concerning the general random-energy model for ionic transport in ionic glasses. Corona effect and electroluminescence in thermal-electric field poling in soda-lime glasses are also investigated. The corona and electroluminescence spectra exhibit noticeable difference only in the 185–300nm region where the former is absent.
