Abstract

In this paper, collapse dynamics of optical vortices, Laguerre-Gaussian modes are produced from 90-fs, 800-nm pulses of a Ti:Sapphire regenerative amplifier using spiral phase plates is investigated experimentally and theoretically. In the presence of azimuthal noise, we find that the beam breaks up into a highly predictable number of filaments as a function of power and topological charge.
