It is shown that an arbitrary nonparaxial laser vortex near a focal plane in the free space should be represented as a discrete superposition of intrinsic vortices possessing elliptical cross sections. The intrinsic vortices, albeit degenerate with respect to the propagation constants, exhibit a characteristic spectrum of singularities and topological phases.
