Abstract Based on the exact solution of Maxwell equations in form a collapsing spherical vector wave specified by an arbitrary function time, we have calculated maximum energy density that can be achieved when focusing extremely short pulses various shapes. It is shown our earlier formula expressing terms spectrum parameters for Gaussian quasi-monochromatic approximately (with accuracy ±40 %) valid main types pulses.
