The term “beam width” may be preferred in applications where the beam does not have circular symmetry. The simplest way to define the width of a beam is to choose two diametrically opposite points at which the irradiance is a specified fraction of the beam’s peak irradiance, and take the distance between them as a measure of the beam’s width.
