The results of investigation of extremely compressed wave packets penetration of air gap under single femtosecond laser pulse filamentation in LiF at anomalous group velocity dispersion are presented. It is revealed by laser coloration method that a single cycle light bullet formed before the gap up to 0.5 mm was recovered after passing some distance behind the gap which increased nonlinearly with the gap length.

Chirped Laser Pulse

In this paper, propagation of a linearly chirped laser pulse in air was investigated to control the remote ionization distance, numerically. Laser spot size and pulse length will be obtained versus effective initial parameters such as positive and negative initial chirp. It is seen that the initial chirp parameter and primary curvature of wave front have important role in focal distance variation and remote ionization. It was also shown that the group velocity dispersion (GVD) could alter and split the positively chirped laser pulse profile after nonlinear self-focusing.
