How Does a Laser Marking System Operate?

Insight Into How The Laser Beam Functions

The very first step in the functioning of a system involves the production of a highly focused beam of laser. The stimulation of the atoms located in the medium, such as a gas, crystal, or fiber, leads to the generation of reasonably coherent electromagnetic waves. Then, by means of mirrors and galvanometers, the laser beam is accurately placed on any material that needs to be marked. The combination of certain materials and the laser’s intensity allows the Jews to make deep engravings on surfaces with the use of discoloration, ablation or simple laser marking. These methods ensure that the sharp markings are permanent.

Tools of a Laser Marking Machine

CO2 laser marking systems use a variety of tools, and one of the most critical is the Laser tube. This tube is sealed and contains a mixture of various gases such as carbon dioxide and even nitrogen, hydrogen, and helium. When an electric current meets these gases, it excites their particles, resulting in the generation of a precise and high-intensity laser beam. This beam is focused using a lens on the target material, which allows for deep and clean marking. Due to the combination of the type of material used and the daily wear of the laser tube, the machine’s efficiency and performance is heavily affected.

Characteristics of Fiber Laser and CO2 Laser 

There is a wide difference between the design and functionalities of fiber laser and co2 laser systems, which also determines the application field of the equipment. Fiber laser operates through a solid-state medium with an optic fiber delivering the beam, which excels at marking metals, plastics, or any other hard surface. They are also regarded for quick operation, accuracy and ease of use maintenance. In contrast, CO2 lasers run on a gas-based medium and are more efficient with non-metallic materials like wood, acrylic, glass, and paper. CO2, being widely used, is also cost-friendly but may not be best at marking metals to the efficiency of its fiber competitor. The application of either of the systems mainly depends on the structure and laser needs for various materials.

What Materials Can a CO2 Laser Marking Machine Process?

Effectiveness on Organic Materials

CO2 laser marking machines are best at processing organic materials since they mark their target non-metallic interfaces with ease. The lasers mentioned above are very effective for the marking or engraving of wood, paper, leather and textiles, and are quite consistent with their results. The application of heat from the laser makes it possible to produce realistic and clear emissions, which are the truest factors for creating intricate patterns, labels and ornamental designs.

Laser Marking For Metal Applications

The only disadvantage of the CO2 laser is that it is best suited mainly to nonmetallic materials, but when an object has been pre-treated or coated, it is able to mark some metals. Moderately, a CO2 laser can mark anodized aluminum or certain painted surfaces. Nevertheless, fiber lasers are still the best option for the direct marking of well-defined metal pieces since they have greater energy efficiency and are able to produce defined markings that are well contrasted without the need for additional surface preparation.

What are the Advantages of a Galvo Laser System?

High-Speed Laser Marking Attributes

The application of Galvo laser systems is widely noted for its rapid laser marking application.
