The Poynting vector in Laguerre–Gaussian beams and the interpretation of their angular momentum density

Abstract We use the local linear momentum density in Laguerre–Gaussian beams to investigate classically the trajectory of the Poynting vector for light of any polarisation. Some of the difficulties of interpretation of the local angular momentum density are discussed.
