摘要：
A plasma channel up to 80 Rayleigh lengths is formed when intense femtosecond laser pulses propagate in air. Two methods, fluorescence measurement and acoustic diagnostics, are used to probe the plasma channel simultaneously. Both methods reveal the evolution of the channel in detail. Compared with the fluorescence measurement, the acoustic method is a convenient approach having higher sensitivity and higher spatial resolution in detecting long plasma channels.
