Abstract
Polymer films doped with 2-(5,5-dimethyl-3-styryl-cyclohex-2-enylidene)-malononitrile chromophore and various sensitizers have been prepared and characterized. The material exhibits high sensitivity in the red region ( at ), a large dynamic range , and large transient two-beam coupling gain . Self-diffraction effects, such as energy and phase coupling, and photoinduced scattering are studied.
