Marking & Engraving
Fiber laser belong to the solid state laser group. They generate a laser beam by means of the so-called seed laser and amplify it in specially designed glass fibers, which are supplied with energy via pump diodes. 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 CO2 lasers with the same emitted average power.
Fiber laser are optimally suited for metal marking by way of annealing, for metal engraving, and for high-contrast plastic markings. Fiber lasers are generally maintenance-free and feature a long service life of at least 100,000 laser hours.
A special type of fiber laser is the MOPA laser, where pulse durations/width are adjustable. This makes the MOPA laser one of the most flexible lasers which can be used for many applications.
