Propagation of laser pulse trains through the air
The propagation of laser pulse trains (LPT) through the atmosphere is analyzed and simulated. The effects of group velocity dispersion, focusing, chirping, and atmospheric turbulence are included in the analysis. The model is general and is solved for pulses longer than several laser wavelengths. We present examples of the propagation of LPTs with parameters chosen to replicate recent experiments which use LPTs to generate rf radiation in the atmosphere. Propagation of LPTs over extended distances is of particular interest. The pulse length of the individual micro-pulses used in the simulation ranges from ~100 fs -100 ps.
