Time-resolved measurements of electron density and plasma diameter of 1 kHz femtosecond laser filament in air
文献摘要：
The temporal evolutions of electron density and plasma diameter of 1 kHz femtosecond laser filament in air are experi-mentally investigated by utilizing a pump-probe longitudinal diffraction method.A model based on scalar diffraction theory is proposed to extract the spatial phase shift of the probe pulse from the diffraction patterns by the laser air plasma channel.The hydrodynamic effect on plasma evolution at 1 kHz filament is included and analyzed.The measured initial peak electron density of～1018 cm-3 in our experimental conditions decays rapidly by nearly two orders of magnitude within 200 ps.Moreover,the plasma channel size rises from 90 μm to 120 μm as the delay time increases.The experimental obser-vation is in agreement with numerical simulation results by solving the rate equations of the charged particles.
