We observe the formation of ring patterns of a focused femtosecond near IR laser pulse propagating in air before the geometrical focal point. These rings are due to the combined effects of self-focusing and defocusing created by the generated plasma via multiphoton/tunnel ionization of air. Qualitative agreement is found with numerical simulations, using input conditions similar to those in the experiment. (C) 2001 Elsevier Science B.V. All rights reserved.
