The application of optical fiber laser marking machine in industry
Industrial production requires high reliability, small volume, quiet and easy to operate.Fiber laser with its layout is compact, light conversion to high, short preheating time, little affected by the situation factors, maintenance free and easy with optical fiber or made light optical lens system coupling strengths favor by common people.Now, optical fiber lasers are gradually replacing the traditional laser with laser marking, laser welding, laser cutting and other leading positions.
In the field of marking, due to the optical fiber lasers with high beam quality and positioning precision of optical fiber marking system is take the place of obedience is not high carbon dioxide laser and xenon lamp pumped Nd: YAG pulsed laser marking system.In taixi and the Japanese market, this kind of substitute is held in a large scale, in Japan alone, the demand is more than 100 each month.According to IPG, the German automaker BMW has purchased their high-power fiber laser for the car door welding line.
China as the world's largest producer of industrial products, the demand for optical fiber laser marking machines is very large, and it is expected to demand more than 2,000 units per year.In the field of laser welding and cutting, the fiber laser has been applied with the development of the above and tens of thousands of watts fiber lasers.
The application of fiber laser in sensor
Compared with other light sources, fiber laser is used as sensor light source has many advantages.First of all, fiber laser has excellent performance such as high utilization, attunement, good stability, compact compact, light weight, easy maintenance and good beam quality.Secondly, the fiber laser can be well coupled with the optical fiber, which is fully compatible with the existing optical fiber devices, and can be tested with full fiber.
Now, fiber sensing based on tunable narrow line wide fiber laser is one of the hot applications in this field.The optical line of the fiber laser is very narrow, has long and dry length, and can be modulated rapidly in frequency.This narrow line wide fiber laser is applied to the diffuse sensing system, which can realize the optical fiber sensing of ultra-long intervals and ultra-high precision.In the United States and Europe, the sensing skills based on tunable narrow line wide fiber lasers have been applied.China is expected to demand more than 100 of these model fiber lasers every year.
The application of optical fiber laser in communication
Fiber laser compared to other types of lasers, the layout is compact, heat dissipation, beam quality, volume, and compatibility with the existing system has obvious advantages, has widespread application in the field of communications.
Rare earth doped fiber as the gain medium of mode-locked fiber lasers can be high repetition rate, pulse width of picosecond and femtosecond magnitude of ultrashort optical pulse, and the lasing wavelength and falls on the best window for optical fiber communication on 1.55 mu m band, is the ambition of high-speed optical communication system light source in the future.Now, the 10GHz and 40 GHz repetition frequency lock mode fiber laser has been developed.Once this communication network is laid out, the demand for this example laser will be enormous.
The application of fiber laser in therapy
Nowadays, used for clinical laser are mostly argon ion laser, co2 laser and YAG laser, but usually they beam quality is not high, has the very big volume, need a huge water cooling system, and settlement and maintenance is very not easy, and that is the fiber laser can be complementary.Since water molecules have a suction peak at 2 mu m, the 2 mu m fiber laser can be used as a surgical procedure to quickly stop the bleeding and avoid the damage to the human body.
