Description

This work involves determining the mathematical character of laser pulse generation, subsequent propagation, and eventual laser matter interaction with ultrashort, high peak intensity laser pulses. Femtosecond pulses at or beyond the terawatt power level are at the center of investigations for either single pulse, or moderate to high repetition rates. Our research includes theoretical physics studies coupled with numerical simulation to understand how ultrashort laser pulse propagate and interact with matter. For example, in one effort our goals are to examine the deterministic and statistical nature of femtosecond laser induced plasma filaments and their resultant propagation process. Proposed work focuses on the mathematics (coupled systems of nonlinear partial differential equations of the nonlinear Schrodinger type) and the physics necessary to describe the process of laser induced plasma formation and electromagnetic field coupling to plasma filaments.
