Such a choice of the longitudinal intensity pattern does imply an interesting freedom, since we can consider more generally any expansion ∑m=−∞∞Bmexp(i2πmz∕L)=F(z)exp[iϕ(z)], quantity ϕ(z) being an arbitrary function of the coordinate z.

The same apparatus could also be used to generate higher-order FWs, when the zero-order Bessel beams in superposition (23) are replaced with higher-order Bessel functions. Experimentally, higher-order Bessel beams can be produced by angular modulation of the slits.

However, when we get complete control over the longitudinal shape, we cannot have total control also over the transverse localization, since our stationary fields are of course constrained to obey the wave equation.
