摘要：

We have observed the signatures of quantum trajectories while generating harmonics in metal plasmas by using a high pulse repetition rate (1-kHz) Ti:sapphire laser source. We present how focusing conditions, laser intensity, plasma concentration, and the chirp of laser radiation influence the observation of separated quantum paths. Our studies demonstrate the clear fingerprints of the separated quantum paths in the case of an ionized medium.
