Abstract

This work details the experimental setup and techniques of the Thomson scattering employed to measure the temporal dynamics of plasma properties in filament plasmas. Additionally, key considerations for accurate measurement are addressed, such as alignment, stray light attenuation, and plasma emission. The setup comprises two perpendicular overlapped laser pulses: a nanosecond probe beam and a femtosecond laser for producing the plasma filament. Their relative delay is varied to reveal the electron density temporal dynamics of the filament in nitrogen at 1 atm. The results are compared to the simulations and show a good quantitative agreement on temporal dynamics of electrons. Lastly, it is shown that filament emission significantly impacts the electron number density estimation.
