What is better, Fiber Laser Marking Machines or CO2? This topic has been discussed in the manufacturing community for many years. Because laser purists insist that CO2 is the better technology, while others are pushing for new innovations in Fiber Laser Marking Machines that insist on the exact opposite. Who is right? Which technology is superior?
The answer lies in the fact that many manufacturers offer both fiber laser and CO2 technology in their mechanical product lines. This is because there are significant
differences in technology and capabilities, as well as their performance in specific materials, thicknesses, and applications. It all comes down to what type of material you want to be cut.
The fiber optic takes the light source from the laser cutting machine’s resonant cavity and transmits it to its CNC-controlled cutting head. The laser is focused through a series of lenses onto the material surface by the cutting head. It emits from the end the fiber optic cable.
The actual method of creating a CO2 laser is the process. A resonator blown at high speed with CO2 gas (turbine, blower) uses a variety o split the ions light particles (usually RF excitation or DC excitation). This causes the light particles to collide and then split at greater intervals.
The CO2 resonator emits enough light to transmit it in a different manner than the fiber optic method. The beam passes through a reflection process, and is then refocused into the “beam pathway delivery system”. This is purified with an “inert gas” to ensure that the path is free from dust and debris that could interfere with the transmission of the laser. After the laser has been reflected onto the cutting heads, it is refocused to emit the beam in the same way as a fiber machine. This uses a series of lenses to refocus the beam and a high speed cutting gas shield to clean the path.
