Laser types in comparison: CO2 laser vs.. fiber laser
With a wavelength of 1..064 micrometers, fiber lasers produce an extremely small focal diameter; as a result their intensity is up to 100 times higher than that of CO 2 lasers with the same emitted average power.. Fiber lasers are optimally suited for metal marking by way of annealing, for metal engraving, and for high-contrast plastic markings..
