WebGaussian beam optics fundamentally incorporates the idea that, the more tightly light is focused, the larger the divergence of the beam. Since the divergence cannot be infinite, there is a minimum spot size for a given wavelength of light. This behavior of light is a consequence of Heisenberg's uncertainty principle.
