title = "Preparation and study of nonlinear optical properties of functionalized DNA thin films",
abstract = "Third order nonlinear optical properties (NLO) of thin films of pure DNA-CTMA complex and of those doped with disperse red 1 (DNA-CTMA-DR1) and copper plithalocyanine (DNA-CTMA-CoPc) chromophores were studied by the optical third harmonic generation and as function of the dopant concentration. The THG measurements, performed in vacuum at 1064 nm fundamental wavelength reveal an one orders of magnitude increase of chi((3)) (-3 omega; omega, omega, omega) susceptibility of the DNA-CTMA complex when doped with 5\% of DR1. This increase is less important for the complex doped with CoPc. For both dopants it doesn't follow the chromophore concentration, as it could be expected. This behavior is interpreted in terms of the influence of local field. The chi((3)) (-3 omega;omega,omega,omega) susceptibility of pure DNA-CTMA complex is about one order of magnitude larger than for silica plate, used as standard.",
