Can the laser marking machine print black and white?

Time:2022-05-26 Views:

 Many people will ask, the laser marking machine can mark black metal, such as stainless steel, but can it be black on the surface of anodized aluminum? The answer is: yes. But a special fiber laser marking machine is required.


     Fiber lasers have become a hot spot in laser physics research in recent years, and are unanimously considered to be a new generation of products that have the potential to completely replace solid-state lasers. Fiber laser refers to a laser that uses rare earth element-doped glass fiber as a gain medium. Fiber laser can be developed on the basis of fiber amplifier: under the action of pump light, it is easy to form high power density in the fiber, resulting in the laser working substance of the laser. The energy level is "number inversion", and when a positive feedback loop is properly added (to form a resonant cavity), the laser oscillation output can be formed. Shenzhen laser marking machine uses laser beams to mark permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "engrave" traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the desired etching pattern. , text, barcodes and other graphics.


     The pulse width of ordinary fiber laser marking machine is not adjustable. If you want to black aluminum oxide, you need to use a fiber laser marking machine with adjustable pulse width. It is also called aluminum black fiber laser marking machine, or mopa technology. Fiber laser marking machine. This kind of fiber laser marking machine is more expensive than the ordinary fiber laser marking machine, so if this function is not necessary, you can also choose the ordinary configuration fiber laser marking machine.
