Ultrashort pulsed laser atmospheric filament properties and microwave radiation inferred from S-band guided wave interaction and self-emission
Edward. L. Ruden, James. E. Wymer, Jennifer. A. Elle +4
The paper measures the electrical conductivity of plasma filaments created by ultrashort laser pulses in air using attenuation of a 3.2 GHz wave in an S‑band waveguide, and combine…

Temperature and mean axial momentum vs. laser intensity of electrons released from O by an 800 nm ultrashort pulsed laser
Edward L. Ruden
The paper presents a semi‑empirical model that predicts the thermalized temperature and average axial momentum of electrons emitted from O₂ molecules when irradiated by an 800 nm u…
