Abstract
IN a series of experiments to investigate threshold retinal damage produced by CW helium–neon lasers (wavelength = 632.8 nm), we have found that lasers with identical beam divergence and output powers but different amplifier/cavity parameters produce different amounts of retinal damage. The source of this discrepancy has been traced to mode locking in one of the lasers used.
