Abstract
In recent years, lasers have been used increasingly in applications involving writing and recording on film or other materials. Although most of the applications involve low-power helium-neon lasers, which produce a few milliwatts in the red (6328A), many, particularly those involving newspaper plate-making and video-disk recording, utilize argon-ion lasers, which produce up to 20 watts in the blue-green spectrum and several watts in the ultraviolet.Keywords
