Abstract :
The effect of poling voltages on the room-temperature stability of the second-order nonlinearity in thermally poled fused silica was investigated. The nonlinearity induced in samples poled with higher voltages was found to be more stable than that induced with lower poling voltages. A charge recombination process through electrons hopping via transition metal ions has been proposed
