Fig. 6: The simulation results of the on-axis plasma density and airflow around the filament.

From: Stable, intense supercontinuum light generation at 1 kHz by electric field assisted femtosecond laser filamentation in air

Fig. 6

a The simulated on-axis laser intensity, plasma density with the laser working at 10 Hz and 1000 Hz. b is the simulated time evolution of the plasma density under different electric fields. c 2D cross-section of the simulated flow fields around the filament without external electric field. The velocity vectors are colored by velocity magnitude (m s−1). The rectangle represents the longitudinal section of the cylindrical filament. The direction of the laser propagation was along the Z axis.The cross-section of the filament was in the XY plane. d is the maximum airflow velocity around the filament when applying different voltages. See the details of the simulation in the ’Methods’
