We demonstrate that the conical refraction of the input elegant Laguerre–Gaussian
beams can be effectively described through generalized Bessel–Gaussian light beams. We
performed numerical simulations and show good agreement between the exact solution and our
proposed Bessel–Gaussian approximation model. Physical clarity of the proposed model has
allowed us to explain the transition of the classical double-ring pattern of conical refraction in the
Lloyd plane into a multi-ring one and predict new phenomenon such as the Raman spot shift and
dependence of the conical refraction ring radius on the value of the orbital angular momentum.
