We demonstrate that a Laguerre-Gauss spectrum of plane waves distribution optimize the variance of the spectrum-bandwidth product. In the space domain, the axial E_z (TM₀₁) and the azimuthal E_ϕ (TE₀₁) have also a Laguerre-Gauss profile that describes correctly some experimental published and calculated results in the focal plane.
