Third-order Nonlinear Optical Properties of Ethylenic Tetrathiafulvalene Derivatives

B. Sahraoui、M. Sylla、J.P. Bourdin 等 7 位作者1995-10-01Journal of Modern Optics

The degenerate four-wave-mixing method is used to measure the second-order hyperpolarizabilities γ of new soluble tetrathiafulvalene (TTF) derivatives. For each material, the study of solutions at various concentrations leads to the choice of an optimum solution: a compromise between ‘low-nonlinearity low-loss’ and ‘h…

Relationships between Hysteresis Measurements and the Constituent Properties of Ceramic Matrix Composites: II, Experimental Studies on Unidirectional Materials

Jean‐Marc Domergue、Emmanuel Vagaggini、A.G. Evans1995-10-01Journal of the American Ceramic Society

The use of hysteresis loop measurements for assessing the constituent properties of unidirectional CMCs is evaluated, using basic theory described in a companion paper. Results are obtained on SiC/CAS and SiC/SiC composites. These materials exhibit very different hysteresis characteristics, reflected in differences in…
