What Is Laser Application

Laser technology is one of the four major scientific inventions in the 20th century, along with atomic energy, semiconductors and computers. Laser has excellent monochromaticity, coherence and directionality, and can accumulate high energy density in a small area, making it particularly suitable for material processing. In the late 1970s and early 1980s, a new laser application technology, laser marking technology, quietly emerged internationally and was rapidly industrialized, becoming one of the largest application areas of laser processing. Laser marking technology uses computer-controlled laser as a processing method. Its basic principle is: a computer controls a high-energy-density focused laser beam to act on the surface of mechanical parts, electronic components, instruments and meters that need to be marked according to a predetermined trajectory, so that the surface material is instantly vaporized or undergoes chemical changes to change color, and text, patterns, etc. with a certain depth or color are etched, thereby leaving a permanent mark on the surface of the workpiece.
As a modern precision processing method, laser marking technology has unparalleled advantages compared with traditional processing methods such as corrosion, electrospark processing, mechanical engraving, and printing:
1. When laser is used as a processing method, there is no processing force between the workpiece and the workpiece. It has the advantages of no contact, no cutting force, and small thermal impact, which ensures the original accuracy of the workpiece. At the same time, it has a wide adaptability to materials, and can make very fine marks on the surface of a variety of materials with very good durability;
2. The laser has good spatial controllability and temporal controllability, and has a large degree of freedom in the material, shape, size and processing environment of the processing object, which is particularly suitable for automated processing and special surface processing. And the processing method is flexible, which can meet the needs of laboratory-style single-item design and the requirements of industrial mass production;
3. The laser engraving is fine, and the lines can reach the millimeter to micron level. The marks made by laser engraving technology are very difficult to imitate and change, which is extremely important for product anti-counterfeiting;
4. The combination of laser processing system and computer numerical control technology can form efficient automated processing equipment, which can print various texts, symbols and patterns, and is easy to design engraving patterns with software, change the marking content, and adapt to the high efficiency and fast-paced requirements of modern production;
5. Laser processing has no pollution source and is a clean, pollution-free and highly environmentally friendly processing technology;
Laser marking technology has been widely used in various industries, opening up broad prospects for high-quality, efficient, pollution-free and low-cost modern processing production. With the continuous expansion of modern laser marking application fields, the requirements for miniaturization, high efficiency and integration of laser manufacturing equipment systems are also higher.
