The working principle of the optical fiber laser marking machine
The optical fiber laser marking machine is made of ytterbium doped double clad fiber as the laser medium, so that the high power fiber laser can get the beam output near the diffraction limit. The optical fiber laser is used as the base film output. The focusing spot diameter is 10 microns, and the laser beam light path is controlled by the computer to control the high-speed scanning mirror to change the light path of the laser beam. Mark. Laser marking is not force and non-contact. It has little effect on the quality of the product. After marking, the font quality is stronger.
