Abstract
A method for avoiding damage to the eyes when using high-power lasers in the eye-transmissible spectral region is provided. By adding a laser or a radiation in the visible spectral region, the intensity of the radiation is increased as a function of time in the shape of a ramp from zero to higher values which lead to a conscious or reflex-type closing of the eyelids This therefore prevents the eyes from being damaged by the subsequent high-power laser beam.
