Low power, air-cooled Argon lasers with internal mirrors are now replacing external mirror designs in most O.E.M. applications. This recent change in design philosophy has been driven by the laser needs of the rapidly growing laser graphics and image handling industries. While these users are now developing more sophisticated systems, they are also improving production and field service economies. For these reasons a need for low cost, Helium-Neon like dependability in O.E.M. Argon lasers has developed. Although the major benefits of this new technology are greatly improved life, reliability, and low cost; there are also improvements in warm-up characteristics, power and beam pointing stability, and reduced low frequency noise. Data illustrating these improved performance characteristics is presented.
