Abstract
Optical vortices, produced by a spiral phase plate, were propagated in free space over long distances in the 1 PW experimental chamber, and characterized in the spatio-temporal framework. Optimization of the low-order distortions by a deformable mirror, allowed to obtain a doughnut in the focus plane of an off-axis parabola.
