LaserStar Blends

LaserStar Blends: Laser Gas Mixtures

Our LaserStar™ gas blends are produced to meet the stringent requirements of the laser processing industry. Available as pure gases or as pre-blended mixtures of helium, nitrogen, carbon dioxide and carbon monoxide, Praxair LaserStar gases are used to generate the beam in a wide variety of carbon dioxide lasers. With a properly designed delivery system, the use of LaserStar gases helps assure optimum laser performance, maximum operating duty cycle, and minimum maintenance costs. See the LaserStar blends we offer below.
