Abstract:

A study of novel nonlinear optical processes is presented, along with comparison with available experimental data. Five key areas were investigated using novel theoretical approaches. Analysis of phase conjugate optics of rare earth doped solids predicts inhomogenous saturation behavior, pair quenching effects and concentration dependent filtering property, in agreement with experiments. Theory of millimeter wave phase conjugation and novel modulation techniques for communication purposes in semiconductor superlattices are described. The physics of self-pumped phase conjugation in resonant systems are quantified, and the demonstration of a self-pumped phase conjugate mirror at diode laser wavelengths is achieved. A theoretical model, based on the Davydov Hamiltonian, gives absorption lineshapes in agreement with experiments, and predicts the onset of bistability and energy transfer in two-beam coupling. An analysis of the role of multiple longitudinal phonon coupling to Wannier excitions yields Fano-like profiles in four-wave mixing spectroscopy.
