Abstract
Dynamics of powerful femtosecond singular-phase pulsed beams in a dielectric medium under the ionization conditions is analyzed numerically. The multiphoton ionization is revealed to contribute to the stable (quasi-soliton) regime of pulse propagation over distances exceeding five diffraction length. Use of the singular beams allows one to reach the larger densities of the light field and generated plasma.
