You can opt for holographic attachments that screw into the laser aperture and feature a white screen front surface. These attachments include an optical element that disperses most of the laser light into a symmetrical pattern diverging around the central beam. This projected pattern serves the purpose of aligning optical elements by ensuring symmetry with the edge of the optic.
