![]() ![]() A resonator, purged with CO2 gasses under high velocity (turbos or blowers) used a variety of methods to split the ions of light particles (typically RF or DC excitement) causing the light particles to collide into each other and split at an even greater intervals. What Is a CO2 Laser?Ī CO2 laser really refers to the method of generation of the laser itself. Purged with cutting gasses such as NO2 and O2 around the laser the material to be machined is quickly vaporized in the intense heart and blown away as particles of dust. In the cutting head the laser is emitted form the end of the fiber optic cable and refocused through a series of focal lenses into a near perfect dot on the material's surface. The fiber receives the light source from the resonator of the laser cutting machine and delivered it to the cutting head which is controlled by the CNC. The fiber beam delivery method greatly simplified the process of building a laser and as such many machines came to the market at greatly reduced prices. The term does not specify how the light source is created (which is different then that of CO2 resonators). What Is a Fiber Laser?Ī Fiber Laser is simply a term used for the fiber optic delivery method of bringing the intense and amplified light source to the cutting head of the laser machine. ![]() ![]() CO2 Lasers however gain an edge when it comes to material types and the flexibility to adapt to a wider range of materials. They achieve this by not having to reflect the beam off of mirrors and refocus the beam through a myriad of lenses, thereby maintaining all of the power being produced at the source. In a previous article, Why the Kilowatt is not the King, we discovered that Fiber Lasers get more power from the resonator, or power source, to the cutting head. Ultimately it comes down to the material you are cutting type and thickness of it. ![]() They do so as they have seen there is a marked difference in the technologies, capabilities and more importantly their performance in certain materials, thicknesses and special applications. But who is right? Which technology is better and how does it affect your bottom line?Ī clue to the answer is the realization that most manufacturers still offer BOTH CO2 and Fiber Laser Technologies in their machinery product offering. Fiber Laser, which is better? This has been a common discussion in manufacturing circles for several years now as Laser purists insist CO2 was the better technology and others promoting the new innovations of Fiber Lasers, insist just the opposite is true. ![]()
