Nonlinear and Correlated Dynamics of the Interaction of Intense Ultra-Short Optical Pulses with Materials: Application to Plasmonics, Nanostructuring, High Harmonic, and THz Generation

Abstract

Developed Quantum Monte-Carlo computer model combined with system of vector nonlinear envelope equations and time dependent Schrodinger Equation and verified against multiple known ultra intense laser interactions with matter. The simulation developed simultaneously describes changes in the material properties and the polarization dynamics of the laser pulse by combining the developed theoretical tools for numerical solution of the time-dependent Schrodinger equation and the system of vector nonlinear envelope equations (VNEE). Photoionization, non-linear polarization and high-harmonic generation (HHG) in semiconductor and dielectric materials will be modeled by solving numerically the time-dependent Schrodinger equation (TDSE) with empirical ionic pseudopotentials to represent the static electronic band structure. Also, Simulated Optical Parametric Oscillator (OPO) single and triple harmonic generation and frequency conversion using an ab initio approach.
