It has been decades for laser pointer to control spin to produce light, but the orbital angular momentum produced in lasers is not so simple. The optical orbital angular momentum is created by twisting the phase of light into a spiral shape, forming a spiral shape. Because the closer to the center of the beam, the distortion…
