Abstract
Third-order nonlinear properties of polymer films doped with triarylmethane dyes have been measured by using third-harmonic generation (THG) for fundamental wavelengths within the range 1 100 nm - 1 600 nm. Our studies show that the triarylmethane dyes Crystal Violet and Ethyl Violet, with a multidirectional charge transfer in their 3-fold symmetry structure (octopolar dimensionality), exhibit large third-order nonlinear coefficient and low residual absorption for harmonic wavelengths, leading to a high conversion efficiencies of THG. The studied films are good candidates for ultra-fast optical correlators.
