We discuss the properties of a novel type of dislocations, called entangled spatio-temporal vortices. Dynamic interferometry method is applied for their registration. We demonstrate that two non-complanar phase modulated beams generate periodical train of spatio-temporal vortices. Propagation dynamics of a spatio-temporal vortex-soliton in defocusing Kerr-like medium is considered as well.
