Abstract
The spectral sensitivity of several common photosensitive materials used in high speed writing applications is described along with response characteristics at specific emission wavelengths of common commercial lasers. A comparison is presented of the design and performance characteristics of helium-cadmium versus air cooled argon-ion lasers used for writing on orthochromatic materials. The laser design simplification opportunities are discussed for helium-cadmium lasers because of the high efficiency and low power density inherent in helium-cadmium lasers. New hard sealed coaxial plasma tube construction emulating helium-neon plasma tube construction has dramatically improved the reliability and shelf lifetime of helium-cadmium lasers.
