Abstract

Optical wave packets are often used as means of energy delivery on a remote target in various applications. The use of shaped optical wave packets can, in principle, enable us to control the intensity distribution and the focus position in the linear and the non-linear propagation regimes. An ideal template for this tailored control is the recently introduced family of cylindrically symmetric accelerating beams [1,2], often referred as circular Airy (CAB) or ring-Airy beams. These wave packets propagate in curved trajectories, exhibit abrupt auto-focus, while at high intensities they reshape into nonlinear intense light-bullets with extremely well defined focal position [3].
