Laser gases 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 occasionally, carbon monoxide, Laser gases are used to generate the laser beam in a wide variety of CO2 lasers. Carbon dioxide lasers must be protected from the problems created by moisture, hydrocarbons, and other contaminants which can be introduced through the gas supply system. These impurities can reduce laser power, create unstable operating characteristics, damage expensive optics, and cause costly downtime. With a properly designed delivery system, the use of Laser gases help assures optimum laser performance, maximum operating duty cycle, and minimum maintenance costs.
