Carrier Based Long Wavelength Electromagnetic Light Bullets, Carrier Shock Initiated Exotic Waveforms and Extreme NLO Pulse Delivery to Targets Extreme NLO Pulse Delivery to Targets
Abstract
The main thrust of this effort was to build a new fundamental theory of LWIR intense ultrashort pulse (USPL) propagation in condensed and gaseous media. A new canonical description of pulse propagation captured by a generalized modified Kadomtsev-Petviashili (MkP) equation. The UPPE equation was extended to include the full HITRAN linear atmospheric refractive index (dispersion) and absorption database. We implemented a 1D/2D bi-directional version of UPPE to address to important problems: 1) reflection of internally generated backward fields or 2) counter-propagating E.M pulses in finite length nonlinear samples. We discovered that microscopic many-body effects introduce a new paradigm for the long range delivery of high energy self-trapped LWIR 10 micron pulses. Moreover, the classical avalanche ionization model does not correctly capture ionization at these long wavelengths and we introduced a new two-temperature model that supported recent joint UCLA-Brookhaven National Laboratory experiment. We concluded a preliminary investigation of the role of nonlinear contributions of clusters of detuned rovibrational transitions in modifying the HITRAN linear response allowing us to explore its impact albeit over few hundred meter propagation ranges. We also implemented a new stable fully anisotropic and semi-conformal FDTD solver and applied it to novel plasmonic and high index dielectric metamaterials.
