Abstract

In this paper, we show our preliminary results in the investigation of the nonlinear optical properties of dye sensitized DNA. We are measuring the nonlinear refractive indices of the DNA with cetyltrimethylammonium (CTMA) surfactant, doped with Rhodamine 610 dissolved in butanol. The measurements are made using the Double Z-Scan method using a femtosecond laser at 1030nm as light source working in mode-locked and un-mode-locked regime respectively for discriminating fast nonlinearities from the slow ones.
