Abstract:We present our results from the measurements of third-order optical nonlinearity in DNA doped Rhodamine 6G/PVA films achieved through Z-scan measurements using ~2 picosecond (ps) pulses at a wavelength of 800 nm. The films demonstrated negative nonlinear refractive index (n 2 ) with magnitudes of (0.065 -2.89) × 10 -14 cm 2 /W with varying concentration of DNA. Open aperture data demonstrated strong two-photon absorption with a magnitude of ~1.6 cm/GW for films doped with 2 wt% of DNA. The recovery time of exc… Show more
