Paper Abstract

The second-order nonlinear susceptibility X(2)xxx its two molecules, an azo dye and a polyene, is measured at various fundamental frequencies, so as to study its frequency dependence. The molecules are deposited on an hydrophilic glass substrate by use of the Langmuir-Blodgett technique. A resonant enhancement of X(2) is observed for both molecules, and the X(2) frequency dependence displays two well separated maxima. The origin of these peaks is discussed in terms of resonance with vibronic levels.
