Laser Vortical Toroidal Propagation

Yet another marvelous discovery of the ubiquity of the toroidal electromagnetic dynamics.

Orbital angular momentum (OAM) vortices (pink ringlike objects) are three-dimensional laser light structures that rotate around a central beam, much like water circles around a drain. Physicists and engineers have studied this type of laser vortex since the 1990s as a tool to help improve microscopy and telecommunications.
