Colloquium - Spatio-temporal optical vortices

Prof. Dr. Howard Milchberg | University of Maryland, College Park, MD, USA

I will describe our discovery of spatio-temporal optical vortices (STOVs), a new type of orbital angular momentum structure that appears spontaneously in the arrested catastrophic collapse of a self-focusing pulse. Although previously unanticipated, STOVs appear to be common and universal, providing a unifying picture of nonlinear self-guided propagation and its robustness. I will also present recent single shot measurements catching an ultrashort STOV-carrying pulse in mid-flight.
