Enhanced stability of the second-order optical nonlinearity in poled glasses
Glasses in a wide range of chemical composition were thermally poled and the stability of the second-order optical nonlinearity induced was studied through isothermal annealing experiments. Enhanced stability was found in aluminosilicate and aluminoborosilicate with respect to silica ~at least a five order of magnitude increase in lifetime!. Such dramatic enhancement was explained by the strong...
متن کاملDynamics of the second-order nonlinearity in thermally poled silica glass
We study the temporal evolution of both the second-order nonlinear coefficient and of the nonlinear thickness in thermally poled silica-glass slides by using a high-resolution all-optical technique. A time delay in the nonlinearity formation is observed, followed by an increase to a maximum, and a final decrease. The thickness is shown to increase at a rate that differs significantly from that ...
متن کاملOptical Properties of Bismuth Tellurite Based Glass
A series of binary tellurite based glasses (Bi(2)O(3))(x) (TeO(2))(100-) (x) was prepared by melt quenching method. The density, molar volume and refractive index increase when bismuth ions Bi(3+) increase, this is due to the increased polarization of the ions Bi(3+) and the enhanced formation of non-bridging oxygen (NBO). The Fourier transform infrared spectroscopy (FTIR) results show the bond...
متن کاملEvaluation of Second Order Nonlinearity in Periodically Poled KTiOPO4 Crystal Using Boyd and Kleinman Theory
The effective nonlinearity ENL of periodically poled KTiOPO4 crystal is precisely measured with SHG experiment at various focusing conditions. The result shows the optimum focusing condition which maximizes the ENL at focusing parameter ξ at around 2.8 and is consistent with Boyd and Kleinman theory. The analysis based on the theory shows the nonlinear optical coefficient d33 of 17.5 [pm/V].
متن کاملHumidity effect on the decay of second-order nonlinearity in thermally poled fused silica.
Type I (GE124) and Type II (KV) fused silica were thermally poled in a vacuum and in air under identical poling conditions. Second-order nonlinear (SON) strength and nonlinear depth were found all to be the same. Samples were then stored in high and low humidity to study their SON stability. The SON of poled GE124 was stable over time despite different poling atmospheres and humidity in storage...
