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. © 2012 Springer-Verlag Berlin Heidelberg.
