Beam shutters, beam polarizers, and beam filters should always be used to limit exposure. The flashlamps in optical pump systems should be shielded to eliminate any direct viewing. Backstops should be diffusely reflecting and fire-resistant target materials. Safety enclosures should be used around microwelding and microdrilling work pieces to contain hazardous reflections from the work area. Microscopic viewing systems used to study the work piece should prevent hazardous levels of reflected laser irradiation back through the optics.
Eye exams are mandatory.
