Paper Abstract

The level of second harmonic generation (SHG) in fused silica can be altered by the addition and removal of water by wet and dry annealing in N2. The magnitude of the effect is sensitive to the lot of material. Maximum SHG occurs with annealing temperatures near 500 degree(s)C with smaller values of SHG occurring for annealing temperatures on either side of 500 degree(s)C. For annealed samples, the SHG has been found to have both surface and bulk components. Preliminary EPR analysis has shown a growth in both the Si and Ge E' centers on either side of a 500 degree(s)C - 600 degree(s)C annealing temperature. Finally, from depoling current data, evidence for a second order `bond effect' along with a third order `hole filling effect' has been found.
