title: Self-action and regularized self-guiding of pulsed Bessel-like beams in air.
abstract: Using computer simulations we explore the dynamics of nonlinear pulsed Bessel-like beams arising from axicon-focused Gaussian beams and circularly apodized beams propagating in air. These pulses exhibit similar self-action. We also note that noninear behavior can occur for these pulses in the absence of significant plasma density. This is especially interesting in light of recent experimental observations of self-guiding without plasma.
