【Abstract】 The Tikhonov regularization method is applied to analyze the lifetime of the plasma channel produced by femtosecond laser pulses propagating in air. Experiments show that by using double laser pulses separated by several nanoseconds, the lifetime of the plasma channel can be prolonged by 5 times that of only using one laser pulse.更多还原
