Open AccessQuasi-steady-state air plasma channel produced by a femtosecond laser pulse sequence
A long air plasma channel can be formed by filamentation of intense femtosecond laser pulses. However, the lifetime of the plasma channel produced by a single femtosecond laser pulse is too short (only a few n...
