摘要: We show that among the multitude of rotating light beams whose complex amplitude can be represented as a linear superposition Laguerre–Gaussian (LG) modes with definite numbers there are zero orbital angular momentum (OAM) and vice versa, multi-mode LG no rotation lacking radially symmetric intensity distribution possess non-zero OAM. Also, we give examples OAM, Bessel new hypergeometric modes. Using an SLM, generate beam OAM for first time.
