Abstract :
Terahertz scattering technique was proposed and used for investigation of dynamics of plasma density in a filament formed in air by femtosecond laser pulses. Two orders of magnitude for 2 ns decay of plasma density were obtained. The kinetic processes responsible for such a fast decay are discussed.
