Thesis Abstract

Application of Femtosecond Optical Tweezers towards Understanding of Complex Systems

This thesis describes applications of femtosecond optical tweezers in different complex systems. Starting from multiple particle trapping, the complexity of the system is increased to the binary mixture and non-Newtonian fluids. The simulation of optical forces and potentials in tweezers, based on the effect of Kerr nonlinearity and thermal effects to achieve experimental situations is also presented. The first two chapters introduce a brief history and various applications of optical tweezers to date followed by basic principles of optical tweezers followed by experimental techniques used in my thesis. The sensing and characterization of optical field directed sequential and reversible cluster formation is explored in the third chapter and considering non-interacting nature, the total number of particles present at the focus is shown to be characterized and calculated from the scattering data successfully. The complexity of the system is increased from the water medium to a binary mixture of water and DMSO. To detect micro heterogeneous structures through optical tweezers experiment as well as from Z-scan experiments. The work is then extended to non-Newtonian solvents and micro heterogeneous nature is probed through different sizes of probing beads at different concentrations of Polyacrylamide, Carbopol, and Laponite solutions. The stability of optically tweezed particles is theoretically simulated and show to be greatly dependent on nonlinear Kerr and thermal effects. This work extends from Rayleigh scattering to the intermediate region using Rayleigh theory and generalized Lorentz-Mie theory and proves to be in close agreement with the experiments.
