A variety of environmental exposure tests were conducted on holographic optical elements. Previous reports from our lab have largely been confined to studies on simple mirror holograms in unconverted format. This study was expanded to include slant-f

We report a series of new optically non-linear organic molecules of stilbene and diphenylacetylene derivatives. We have measured their powder second-harmonic generation efficiency and, in certain cases, the second-order molecular polarizability, β.

Phase-matched two-photon excited (TPE) fluorescence and second-harmonic generation (SHG) are used to determine the transvere polariton dispersion curves and longitudinal exciton associated with the 31475 cm − a -exciton of naphthalene. Crystal angl

The problem of determining the contribution of the exciton–photon coupling to the absorption line shape or width of an exciton is addressed. In this regard, both the spatially homogeneous (polariton) and inhomogeneous wave models are considered. Fo
