What is a CO2 Laser Cutting Machine?

How does a CO2 laser cutting machine work?

A CO2 laser cutting machine works on the fundamentals of generating and manipulating a laser with extreme precision. A mixture of gas, predominantly carbon dioxide (CO2), nitrogen, helium, and occasionally hydrogen or xenon, is electrically activated in a sealed tube, resulting in a CO2 laser cutter that generates a concentrated beam of infrared light. It is then the CO2 laser cutter that produces a focused beam of infrared light.

A myriad of mirrors and a focusing lens are utilized to direct the beam towards the material to be cut. A lens is capable of focusing the beam to a specified point, which, in turn, amplifies the power as the laser is increased in intensity. The material can be cut deeply and cleanly in milliseconds, thanks to the intense energy the laser adds, which leads to heating the material to its vaporization or melting point. Thus, a clean cut can be attained because the gas commonly used to blow the molten material away, which is frequently nitrogen or oxygen, ensures smooth edges.

One of the most important benchmarks of performance in CO2 lasers is their wavelength, which lies around 10.6 microns. This enables CO2 lasers to perform exceptionally well in cutting wood, acrylic, plastic, glass, and textiles.
