Temporal evolution of femtosecond laser induced plasma filament in air and N2
We present single shot, high resolution, time-resolved measurements of the relaxation of laser induced plasma filaments in air and in N2 gas. Based on the measurements of the time dependent electromagnetic signal in a waveguide, an accurate and simple derivation of the electron density in the filame...

| description | We present single shot, high resolution, time-resolved measurements of the relaxation of laser induced plasma filaments in air and in N2 gas. Based on the measurements of the time dependent electromagnetic signal in a waveguide, an accurate and simple derivation of the electron density in the filament is demonstrated. This experimental method does not require prior knowledge of filament dimensions or control over its exact spatial location. The experimental results are compared to numerical simulations of air plasma chemistry. Results reveal the role of various decay mechanisms including the importance of O4+ molecular levels. |
