Usually to aline optics safely, low power laser which can safely operated without safety goggles is substituted for higher power laser during alinement procedure. Need for lower power substitute laser can be eliminated by painting target area with commercial paint which fluoresces strongly in red or yellow portion of spectrum when excited by argon laser beam.
Fluorescent paint simplifies laser-beam alinement
