Stimulated by a recent investigation of the Wigner distribution function of a Lorentz–Gauss beam, we present closed-form expression for such a function at the initial plane, which is alternative to that deduced in the aforementioned investigation. Such an expression can be usefully exploited to fully account for the Wigner-plane dynamics of Lorentz–Gauss beams as far as the paraxial propagation is concerned.
