The wave front of Laguerre-Gauss beams carrying orbital angular momentum, rotates at optical frequency around the propagation axis. By analogy, one may think of optical beams in free space whose transverse spatial field distribution rotates with time at variable speed. In fact, we propose two different implementations that allow to set the rotation frequency to different values ranging from some Hz to a few GHz. The study of these beams may extend the understanding of orbital angular momentum origin and effects. Here we consider the physical properties, as linear and angular momentum, of rotating beams and discuss potential applications.
