The carbon dioxide laser, as the name suggests, uses carbon dioxide as its main component. It is one of the most powerful continuous wave laser cutting machines. The utility alongwith the economy of its use makes this laser as one of the most thicker metal in the industry. It is regularly used in cutting as well as welding. The low power lasers are used in engraving. The efficiency of this laser is also quiet commendable. CO2 Laser Cutting Machine is a mature technology in the market place.
The CO2 laser operates on infrared radiations; hence specialized construction becomes a necessity. The mirrors in the laser are silvered and its windows and lenses are made of zinc selenide or germanium. Gold and zinc selenide windows and lenses are used for high power lasers. Some lasers that operate in extremely rugged and unfriendly conditions use diamond mirrors which have far better optical properties and this helps in transmission of high power lasers.
The assembly consists of a gas discharge with a total reflector on one of its ends and the output coupler at the output end. There are laser focusing lenses alongwith the partial and total reflectors. Mirrors are placed at the front, rear and in the corners. The laser beam comes out of the device from the copper nozzle tip.
