CO2 Laser Cutting Machine produce a laser beam in a glass tube that is sealed and filled with carbon dioxide. A high current is sent through the tube, which creates a reaction with the CO2, increasing the energy of the gas particles so that they produce light. When you create light with this level of brightness, the byproduct is intense heat. This heat is strong enough to melt materials with enormously high melting points.
There’s a partially reflective mirror at one end of the tube and a fully reflective mirror on the other side. Light is reflected backward and forwards across the length of the tube. These mirrors help to intensify the light so that it can vaporize most materials. Once the light is bright enough, it passes through the partially reflective mirror. The full mirror guides the laser beam out of the tube and toward a subset of mirrors that the machine uses to create the desired design.
The final mirror is on the inside of the laser head, and it directs the laser through the focus lens onto the material you’re working on. The role of the focus lens is to refine the laser’s pathway so it’s focused on an exact spot. This extra focusing process is what makes a CO2 Laser Cutting Machine able to produce such precise and clean finishes on a broad range of materials.
