Abstract
Polymer films doped with ethyl-3-styryl-cyclohex-2-enylidene)-malononi trile chromophore and various sensitizers have been prepared and chara cterized. The material exhibits high sensitivity in the red region (S = 0.26 cm(2)/J at lambda = 633 nm), a large dynamic range (Delta n = - 0.05), and large transient two-beam coupling gain (G = 110 cm(-1)). Se lf-diffraction effects, such as energy and phase coupling, and photoin duced scattering are studied. (C) 1997 Optical Society of America.
