Working Principle Of Mopa Laser Marking Machine
As an advanced marking equipment, MOPA (adjustable pulse width) fiber laser has excellent pulse shape control capabilities. Compared with Q-switched fiber lasers, the pulse frequency and pulse width of MOPA fiber lasers are independently controllable. By adjusting these two laser parameters, high peak power output can be achieved and applied to a wider range of materials.
The pulse width of MOPA laser marking machine M1 can be adjusted between 4-200ns, and the pulse width of M6 can be adjusted between 2-200ns. The pulse width range of ordinary fiber laser marking machines is 118-126ns. It can be seen that the pulse width adjustment range of the MOPA laser marking machine is wider, which also explains why some products cannot achieve the ideal effect when using ordinary fiber laser marking machines, but can be achieved with the MOPA laser marking machine .
Application Scope Of MOPA Laser Marking Machine
MOPA laser marking machine is suitable for fine marking process of metal and non-metal materials. Whether it is laser engraving of digital product parts, mobile phone buttons, translucent buttons, mobile phone casings, button panels, electronic components, oxidation, plastic marking, or surface treatments such as handicrafts and gifts, oxidation treatment, coating, electroplating and spraying, MOPA laser marking All machines can handle it easily.
Main application areas of MOPA laser marking machine
1. Stainless steel color marking: MOPA laser marking machine performs color marking on stainless steel materials, with vivid effects and rich colors, which improves the appearance quality of the product.
2. Alumina blackening: MOPA laser marking machine can blacken alumina materials to make the surface of the product appear black and increase the texture of the product.
3. Stripping anodes and coatings: The MOPA laser marking machine can accurately strip off anodes and coatings to prepare for subsequent processes.
4. Semiconductor and electronics industry: In the semiconductor and electronics industries, MOPA laser marking machines can precisely mark sensitive materials to meet the precision and aesthetic requirements of electronic products.
5. Marking of plastics and other sensitive materials: MOPA laser marking machine marks plastics and other sensitive materials without causing damage to the materials, ensuring the integrity of the product.
6. PVC plastic pipe industry: MOPA laser marking machine marks PVC plastic pipes with clear writing for easy product identification.
Things to note when purchasing MOPA laser marking machine
When purchasing a MOPA laser marking machine, some customers often hope that its processing speed can be consistent with that of ordinary fiber laser marking machines. However, this expectation is often difficult to achieve. Because MOPA laser marking machines use completely different technologies from ordinary fiber laser marking machines. When engraving color effects, the MOPA laser marking machine needs to mark with minimal shadow effects under high frequency. Although higher engraving resolution can be obtained from this, its engraving speed is relatively slow. In addition, in terms of metal deep engraving, the MOPA laser marking machine has no obvious advantages. Since the single pulse energy is not high, its engraving effect is more delicate than that of ordinary laser marking machines. Of course, we cannot ignore the advantages of MOPA laser marking machines. It can produce high-resolution marks when engraving colorful effects, making the pattern clearer and more realistic. In addition, MOPA laser marking machines also have significant advantages in engraving non-metallic materials and can achieve fast and efficient marking.
Therefore, when choosing a MOPA laser marking machine, customers need to weigh it based on their actual needs. If you need high-resolution color marking, or quick marking on non-metallic materials, a MOPA laser marking machine may be a good choice. If you need deep engraving on large-scale metal materials, then a regular fiber laser marking machine may be more suitable for your needs.
In order to help you better select and configure a MOPA laser marking machine that suits your needs, our professional team at Legent Laser is willing to provide you with a full range of services.
