Application of Two-Photon Fluorescence Measurement on Pulse Characterization during Femtosecond Laser Filamentation in Air
This work proposes a diagnostic method, which is based on two-photon fluorescence measurement, to study the temporal characteristic of a laser pulse undergoing filamentation in air. The results show that the pulse duration, chirp rate and beam radius could be retrieved simultaneously. This simple technique is useful in practice to trace the underlying dynamics of filamentation in air.
