Gaussian laser beams have power intensities in the shape of a bell curve (Gaussian).
This means that the nominal diameter doesn’t include 100% of the laser beam’s power. A small portion of the power is contained in the edges, or wings, that spread past the nominal beam diameter. This is a simple calculator to see how much of the laser beam will pass through a given aperture.
