▶ CO2 VS Fiber Laser: Which One Suits Cutting Acrylic
For cutting acrylic, a CO2 Laser is definitely the best choice due to its inherent optical property.
As you can see in the table, CO2 lasers typically produce a focused beam at a wavelength of around 10.6 micrometers, which is readily absorbed by acrylic. However, fiber lasers operate at a wavelength of around 1 micrometer, which is not fully absorbed by wood compared to CO2 lasers. So if you want to cut or mark on metal, the fiber laser is great. But for these non-metal like wood, acrylic, textile, CO2 laser cutting effect is incomparable.
