CO2 lasers are more powerful than diode lasers because their common optical power starts from 30-40W. You can find desktop CO2 lasers in the power range of 30-60W. It is more than enough to cut thick plywood or hardwood up to 20mm even more in only one pass.

In a CO2 laser cutting machine, there is a glass tube filled with a mixture of gasses, including nitrogen and CO2. When the electricity passes through this tube, it produces laser beams. Then, these beams are passed through mirrors and lenses to merge them at a spot. The laser tube has a lifespan of around 1,000 to 10,000 hours. After that, it is replaced by a new one.

Benefits of Laser Cutting Wood

Laser cutting wood offers several advantages over traditional cutting methods. Firstly, it enables intricate and precise cuts, allowing for the creation of complex designs and detailed patterns. The laser beam’s high accuracy and narrow kerf width contribute to the production of clean and sharp edges. Additionally, laser cutting is a non-contact process, minimizing the risk of material distortion or damage. Compared to conventional sawing or routing techniques, laser cutting produces minimal waste and reduces the need for secondary finishing processes. Another advantage is the versatility of laser cutting, as it can be used on various types of wood, including plywood, MDF (medium-density fiberboard), hardwood, and veneer.
