Basic principles of laser marking machine

A laser marking machine is a device that uses a laser beam to mark, etch, or cut the surface of a workpiece. The basic principle involves the emission, focusing, and action of laser light on the workpiece surface. The following are the basic principles of laser marking machines:

Laser emission: Laser marking machines use laser generators as light sources. Laser generators usually use materials such as gas, solid, or semiconductor to generate laser light through energy level transitions. These laser generators can release high-energy, high-purity beams in a very short time.
Modulation of laser: The laser beam emitted by the laser generator is modulated, and power control, frequency adjustment, and pulse width adjustment can be performed as needed. This modulation enables the laser to achieve optimal results under different process requirements.
Focusing of the beam: The laser marking machine focuses the laser beam to a very small focus through the optical system. The focused laser beam can reach extremely high energy density to produce the desired marking, etching, or cutting effects on the workpiece surface.
Acting on the workpiece surface: The focused laser beam is guided to the workpiece surface. By controlling the movement path and parameters of the laser beam, various shapes of marks, text, or patterns can be formed on the workpiece surface. At the same time, the high energy of the laser can also produce effects such as vaporization, heat melting, or chemical reactions on the surface of the workpiece to achieve different processing effects.

In general, laser marking machines use the high energy, high precision, and non-contact characteristics of laser to achieve fine processing and marking of workpiece surfaces. After long-term stable operation of the laser marking machine, the machine needs to be maintained and repaired to ensure that the machine can perform at its best.
