CO2 Laser vs Fiber Laser Marking Machine: Pros and Cons ..
For 1 mm, fiber lasers can cut up to 6 times faster than CO 2 lasers.. For 5 mm paper, the difference is reduced to about 2 times.. The cutting speed of thin sheets can increase by 2-3 times by increasing the power of the laser source to 2kW.. The CO2 laser can cut thin sheets at a faster rate than the fiber laser..
