Abstract
Since the seventies the ability of laser pulses to trigger and guide electric discharges has attracted the interest of the scientific community [1]. Such interest has been supported by the large number of applications associated to electric discharges and by the possibility of lightening control [2–4]. Up to now, discharge control has been performed with Gaussian-like beams or filaments, and hence the discharge path always followed a straight line. Recently however, it has been pointed out that optical beams can propagate along trajectories different from straight lines. It has been shown for instance that Airy beams are featured by an intense peak that propagates along a curved trajectory [5–7].
