Frequency modulation of THz emission from a laser filament array
Sean D. McGuire, Mikhail N. Shneider
A simple traveling wave antenna model is used to theoretically study emission from an array of filaments. Both transverse and longitudinal arrays of filaments are considered. The a…

Axisymmetric model for 1-color laser filament THz emission
Sean D. McGuire, Mikhail N. Shneider
A 3D axisymmetric model for laser beam propagation in air is proposed for use with THz emission calculations. The model accounts for nonlinear propagation of the femtosecond pulse…
