What’s the Difference Between Fiber Lasers and CO2 Lasers?

The two most commonly used lasers in metal fabrication are fiber lasers and CO2 lasers. Here at Serra Laser, we have a wide range of lasers to accommodate any project, large or small, and we always utilize state-of-the-art technology to ensure that your job is done right. That’s why we have both fiber and CO2 lasers in our shop. Here’s a brief guide to understanding the difference between the two.

CO2 Lasers

CO2 lasers have been on the market longer, but that doesn’t meant that they’re an outdated piece of technology. In fact, CO2 lasers are constantly developing in order to increase precision, efficiency, and quality of finish. For fabricators utilizing thick sheets of metal, CO2 lasers are still the most effective and efficient approach to cutting. CO2 lasers create cuts significantly faster when cutting sheets over 2mm thick in a straight line. In our facility, we deal with materials as thick as 1 inch, which often call for a CO2 laser’s superior cutting time and power. CO2 lasers also provide a better finish and cleaner edge when working with thicker materials.

Fiber Lasers

Fiber lasers channel and amplify light using fiber optic cables. Light is then focused using a lens, which focuses this powerful beam onto the material that needs to be cut.

Fiber lasers are a newer technology, and as such have some impressive improvements over former options. For example, using the amplification method specified above, fiber lasers are usually more energy efficient, using as little as a third of the energy needed for CO2 lasers. Fiber lasers are also easier to maintain, eliminating the need for mirror cleanings, beam alignments, bellows checks, and other precautions that are necessitated with each use of CO2 lasers. Fiber lasers are also great for use on reflective materials like aluminum, brass, and copper as the beam is more easily absorbed and less likely to reflect.

Both Laser Options Create Beautiful, Consistent Results

Whether your project is better executed utilizing a CO2 or fiber laser, here at Serra Laser, we have the capabilities to adapt. We utilize the most cutting-edge technology to ensure that you get the results you need. At our facility, we’re able to work on bulk batches with a quick turnaround time and perfectly consistent end results. Our laser cutting services work with any material, from steel, brass, and titanium, to acrylic and wood.
