- Аннотация: The promising application of femtosecond laser filamentation in atmospheric remote sensing brings imperativedemand for diagnosing and controlling the spatiotemporal dynamics of long-distance filamentation. Here, theacoustic method was adopted to quantitatively diagnose the long-distance filamentation of femtosecond pulsesmanipulated by energy and temporal domain. The onset and length of filament can be conveniently obtainedfrom a simple analytic formula based on reasonable approximation and further demonstrated by the experimentalresults. The influence of pulse energy and initial pulse chirp under three different focal lengths (~10 m,20 m, and 30 m) on the filamentation in the air were studied experimentally. These findings provide a guidingsignificance for the optimal control of the long-distance propagation of filament, thereby laying a firm foundationfor femtosecond laser-based atmospheric remote sensing.
