What is laser marking?
"Laser marking" stands for marking or labeling of workpieces and materials with a laser beam. In this regard, different processes are distinguished, such as engraving, removing, staining, annealing and foaming. Depending on the material and the quality requirement, each of these procedures has its own advantages and disadvantages.

How does a laser work?
Laser technology basics
All lasers consist of three components:
1.An external pump source
2.The active laser medium
3.The resonator
The pump source guides external energy to the laser.
The active laser medium is located on the inside of the laser. Depending on the design, the laser medium can consist of a gas mixture CO2 laser marking machine (https://www.stylecnc.com/co2-laser-marking-machine/), of a crystal body YAG laser makring machine (YAG laser) or fiber laser marking machine (https://www.stylecnc.com/fiber-laser-marking-machine/). When energy is fed to the laser medium through the pump, it emits energy in the form of radiation.
The active laser medium is located between two mirrors, the "resonator". One of these mirrors is a one-way mirror. The radiation of the active laser medium is amplified in the resonator. At the same time, only a certain radiation can leave the resonator through the one-way mirror. This bundled radiation is the laser radiation.
