OPTICAL NONLINEAR SUSCEPTIBILITIES OF BERYLLIUM OXIDE

Abstract
The nonlinear coefficients of beryllium oxide measured relative to quartz by the Maker fringe technique are d31(BeO) = ± (0.46 ± 0.03)d11 (SiO2) and d33(BeO) = ± (0.63 ± 0.04)d11 (SiO2) for a fundamental beam at 1.064μ. A simple model accounting for the value of the ratio d31(BeO) / d33(BeO) is proposed.
