Abstract : This one year of seed funding leveraged new and exciting theory/simulation predictions of a new paradigm for long range USP propagation arising as a key research breakthrough of our AFOSR MURI that ended in November 2015 to extend the study of high power mid-IR filament delivery over kilometer ranges. Our in house ultrashort pulse simulation tool was used to provide basic research support for studying atmospheric propagation of a high energy Joule-level few picosecond to sub-picosecond pulsed CO2 laser system being planned within a new DOD joint initiative of AFOSR, AFRL and NRL. Our research focused on understanding the physics of filament creation, propagation at long wavelengths and explored the feasibility sustaining multiple terawatts of power within a single light filament.
