14. In most cases, it is not desired that the aperture be placed at the waist of the Gaussian or Bessel–Gauss beam. How-ever, in certain circumstances, that is, when a laser beam is focused through a finite-aperture lens or a pinhole, the waist size of the beam is on the order of the aperture size.
