3 October 1994 Characterization of the second-order nonlinearity in poled fused silica
Author Affiliations +
Second harmonic generation is used to characterize the second order nonlinearity induced by thermal electric field poling in fused silica. The uniformity of the poled region is improved by using an evaporated rather than a machined poling electrode configuration. The effective thickness L and strength of the nonlinear coefficient d33 of the nonlinear region is estimated using Maker fringes excited through a prism pair.
