Measurements and simulations show that X-waves are spontaneously generated during filamentation in air. This explains the sub-diffractive propagation of filaments beyond the end of the plasma channel generated by multiphoton ionization. © 2008 Optical Society of America.

Abstract
Measurements and simulations show that X-waves are spontaneously generated during filamentation in air. This explains the sub-diffractive propagation of filaments beyond the end of the plasma channel generated by multiphoton ionization. © 2008 Optical Society of America.
