Now, fiber lasers are gradually replacing traditional lasers in the leading positions in laser marking, laser welding, and laser cutting. In the field of marking, fiber lasers have higher beam quality and positioning accuracy.
The application of fiber laser marking machine in industry. Industrial production requires lasers with high reliability, small size, quietness, and easy manipulation. Fiber lasers have attracted people’s attention because of their compact layout, high light conversion compliance, short warm-up time, little influence from situational factors, maintenance-free, and easy coupling with optical fibers or optical lenses to form a light guide system.
Now, fiber laser pointer are gradually replacing traditional lasers in the leading positions in laser marking, laser welding, and laser cutting. In the field of marking, due to the high beam quality and positioning accuracy of fiber lasers, fiber marking systems are replacing the Nd: YAG pulsed laser marking systems pumped by carbon dioxide lasers and xenon lamps, which are not highly compliant; in the Western Thai and Japanese markets , This kind of replacement is held in the scope of integrity, in Japan alone, the monthly demand exceeds 100 units.
As the world’s largest industrial manufacturing country, the demand for fiber laser marking machines is very huge, and it is estimated that there will be a demand for more than 2,000 units each year. In the field of laser welding and cutting, with the successful development of fiber lasers of thousands of watts or even tens of thousands of watts, fiber lasers have also been applied. Earlier, IPG reported that the German BMW Motor Company purchased their high-power fiber laser for use in the door welding production line.
The application of fiber laser in sensing. Compared with other light sources, fiber lasers have many advantages when used as sensing light sources. First, fiber lasers have excellent performance such as high usefulness, tunability, good stability, compactness, light weight, easy maintenance and good beam quality. Secondly, the fiber laser can be well coupled with the fiber, is fully compatible with the existing fiber devices, and can perform all-fiber testing.
Now, fiber sensing based on tunable narrow linewidth fiber green laser pointer is one of the hottest applications in this field. The optical fiber laser of this example has a narrow spectral line width, an ultra-long correlation length, and can quickly modulate the frequency. Applying this narrow linewidth fiber laser to the diffuse sensing system can realize ultra-long interval, ultra-high precision fiber sensing. In the United States and Europe, this sensing technology based on a tunable narrow-linewidth fiber laser is widely used in territorial security and tension monitoring, kerosene/natural gas pipeline monitoring, and underwater sonar detection. It is estimated that the demand for this example fiber laser will be more than 100 units each year.
