Abstract:
It is shown that among multimode rotating laser beams, whereby the complex amplitude can be represented as a linear superposition of Laguerre-Gauss modes with particular numbers, there are some light beams with zero of the orbital angular momentum. Besides, we look into examples of rotating laser beams with the zero orbital angular momentum represented as a superposition of Bessel modes and hypergeometric modes. A rotating Bessel beam with the zero orbital angular momentum was first generated by a liquid crystal microdisplay.

Key words:
orbital angular momentum (OAM), Laguerre-Gauss modes, Bessel modes, hypergeometric modes, superposition, optical rotation with zero OAM.
