Carbon dioxide lasers are one of the most powerful lasers ever constructed. The word "LASER" stands for Light Amplification by Stimulated Emission of Radiation. Lasers are devices that amplify light and produce light beams, ranging from infrared to ultraviolet. A light beam is consistent when its waves or photons, increase while mixing together. Laser light can be extremely intense, highly directional and very pure in color. Gas lasers such as the carbon dioxide laser is made active by ultraviolet light, electron beams, electric current. Lasers, in the future, will be used tremendously in the hospitals, research, military, and even in our homes.
             Albert Einstein, in 1917, was the first to develop the process for laser action. In 1958, American physicists Arthur Schawlow and Charles Hard develop the working principles of lasers. Another American physicist Theodore Maiman observed the first laser action in a solid ruby, in 1960. A year later a helium-neon gas laser was constructed by Ali Javan. Then in 1966 a liquid laser was built by Peter Sorokin. With the inventions of different types of lasers developed by the previous mentioned physicist, lasers are generally classified as solid state, gas, semiconductor, or liquid.
             The laser of a gas can be a pure gas, a mixture of gases or even metal vapor and is contained in a cylindrical glass or tube. Two mirrors are positioned outside the ends of the tube to form the laser. Gas lasers are pumped by ultra violet light, electron beams, electric current, or chemical reactions(Britannica Junior Encyclop 'dia v.9 p.72) The carbon dioxide lasers are very efficient and they are the most powerful laser. These high powered lasers are measured in WATTs and KILOWATTS. Not mattering the size of the laser, a laser the size of a neon tube will constantly produce for ten seconds of WATTs.
             A larger laser is mainly used in the metalworking f
