Rotate about which axis? Do you mean like with scanning laser displays?hackhard said:
rotates about axis normal to laser beam .berkeman said:
You mean there is only one point in space (filled with some scattering medium like air), where the beam always passes? You will get an approx. linear fall-off from that point. Maybe if instead of scattering you use some form of excitation of the medium, you might get different effects.hackhard said:

A rotating coherent laser beam is a laser beam that has a circular polarization and rotates around its axis. It is created by combining two beams with opposite circular polarizations, resulting in a beam with a rotating electric field.
A rotating coherent laser beam is created by using a quarter-wave plate to convert a linearly polarized laser beam into a circularly polarized beam. This beam is then combined with another beam that has the opposite circular polarization using a polarizing beam splitter, resulting in a rotating coherent laser beam.
A rotating coherent laser beam has various applications in optics and photonics, such as in optical tweezers, optical communication, and optical coherence tomography. It is also used in research for studying the properties of light and for creating 3D optical lattices.
The rotation speed of a rotating coherent laser beam can be controlled by adjusting the relative phase between the two circularly polarized beams that are combined to create it. This can be done using a wave plate, which changes the phase of the laser beam.
Yes, a rotating coherent laser beam can be used for cutting or drilling materials. Its high intensity and precise rotation allow for precise and controlled material removal, making it useful in industrial applications such as laser cutting and drilling.
