Abstract
We report the observation of self-guided propagation of 120 fs, 0.56 mJ infrared pulse in air for distances greater than a meter (more than thirty Rayleigh Lengths). The numerical simulations demonstrates the this localized structure corresponds to a Townes soliton, specially stable under these conditions.
