摘要: We have measured the time-dependent electrical resistance of a plasma channel created in air by self-guiding TW femtosecond laser pulse. The conductivity over 200 ns time interval has been determined from nonlinear low-inductance circuit model experiment. incorporates decay kinetics and initial electron density.
