Can the laser marking machine mark black and white characters?

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 alumina? The answer is: yes. But need fiber laser marking machine.

Fiber lasers have become a hot topic in laser physics research in recent years, and are considered to be a potential replacement for 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, high power density is easily formed in the fiber, resulting in the laser energy of the laser working material. "Particle number inversion", when a positive feedback loop (constituting a resonant cavity) is properly added, the laser oscillation output can be formed. Shenzhen laser marking machine uses a laser beam to mark lasting marks on the surface of a variety of different substances. The effect of marking is to expose the material through the evaporation of the surface material, or to "engrave" traces through the physical change 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, barcode and other types of graphics.

Can the laser marking machine print black and white?

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 you don't need this kind of function, you can also choose the ordinary configuration fiber laser marking machine.
