Paper Abstract

Light beams rotating about their axis can be created using rotating optical elements. We analyze the properties of rotating beams by expanding the mode function in eigenfunctions of angular momentum. Both the spin angular momentum, arising from the polarization, and orbital angular momentum, arising from the circulating phase gradient, are considered.
