Abstract
In this paper, we examine the Laguerre-Whittaker-Gauss (LWGBs) propagation in a gradient index (GRIN) medium. The Collins integral is used to get the analytical expression of LWGBs across this optical medium. Numerical demonstrations of the intensity characteristics of these beams in a GRIN medium are presented. The findings demonstrate that the gradient index parameter β and the incoming beam parameters m, l, n and \(\omega_{0}\) have an impact on the behavior of the LWGBs. Furthermore, it is demonstrated that when β grows, the period L decreases and the outgoing beam fluctuates regularly with the propagation distance. The findings presented in this study have applications in optical micromanipulation, free-space optical communications, optical control, and optical trapping.
