Computational Nonlinear Optics: Femtosecond Atmospheric Light String Applications

Abstract

The main technical achievement of the project was the development of a comprehensive vector Maxwell unidirectional laser pulse propagator to accurately simulate intense ultra-short atmospheric light strings, white-light super-continuum generation across a broad landscape of applications, short range THz emission from plasma channels left in the wake of critically-collapsing light strings, nonlinear X- and O-wave generation in air, water and condensed matter and super-continuum shaping in sub-micron diameter fiber cores and photonic crystal fibers. The propagator model is broadly inclusive, allowing for the first time the capability to propagate optical carrier resolved, 3D space and time laser pulses over many meter distances. Furthermore it allows seamless transition to all know prior ultra-short pulse propagators in the literature thereby clearly identifying the physical limitations of each. Funding from the project also enabled the initial development of a full 3D FDTD vector Maxwell space and time grid refinement algorithm. It is anticipated that the propagator developed in this project will need to be fully interfaced to a Maxwell solver in anticipation of future extreme nonlinear optics applications.
