Study of the excited state dynamics to improve the optical limiting performance of tetra tolyl porphmiting devices show linear absorbance at lower intensities and limit to a threshold transmittance at higher intensities due to reverse saturation of absorption. Such a nonlinear absorption can be achieved through excited state absorption (ESA) and two-photon absorption (TPA) in porphyrins. As the po

Multiphoton processes in laser fieldfor studying strongly perturbed dynamics of the simplest quantum systems. Due to these developments, amazing advances have been made by applying this new tool in spectroscopy. The area of non-linear optics has now come to the forefront and is in a stage of rapid expansion.

Femtosecond ionization of CH3CN-NaI and CH3CN-Cslstates when aggregated with a single molecule of acetonitrile (CH.CN). The probe signal is obtained by femtosecond ionization of the diatomic chromophore. The addition of acetonitrile is found to change greatly the ionization signal of the free molecule suggesting strong modification of the reaction dynamics.
