What are the main application technologies of fiber laser cutting machine?

The fiber generator is an important part of the fiber laser cutting machine. Since the birth of the fiber generator, fiber laser cutting has gradually entered people's field of vision and has been widely used. Compared with the traditional metal cutting machine, the fiber laser cutting machine is awarded the title of 'third-generation laser cutting machine' for its fast cutting speed, high photoelectric conversion rate, good cutting effect, maintenance cost and low use cost. Then fiber laser cutting What are the main technologies that the machine is mainly applied to? The following Wuhan High Energy Laser will introduce to you. There are five main application technologies for fiber laser cutting machines; 1. Special fiber technology All fiber lasers need to use double-clad and double-clad photosensitive fiber, energy Transmission fiber, source fiber, and other special fibers. With the continuous improvement of output power, the technical requirements for special fibers are getting higher and higher. Therefore, the development of special fibers will play an important role in the development of fiber lasers. The development of special optical fibers will make active optical fibers have higher gains, withstand greater power density, and absorb pump light more effectively; it will make the production of gratings easier, the stability of the gratings better, and the gratings in the optical fiber. The use of lasers is more extensive; it will enable energy transmission fibers to transmit higher power, high-power lasers can be transmitted longer distances, and the wavelength range that can be transmitted continues to expand; it will make pump coupling easier to achieve and bearable The pump power is higher and the loss is smaller. 2. Cladding pump coupling technology of all-fiber lasers The clad pump coupling technology of all-fiber lasers has an immeasurable effect on determining the performance and level of fiber lasers. Fibers used for high-power all-fiber lasers Both pump coupling devices and fiber power combining devices are used under very high power conditions. Their coupling must be very high, loss must be small, and the power must be large, and the number of input light paths must be as large as possible Many. Under so many extreme conditions, it is very difficult to make high-quality pump coupling devices and power combining devices. However, there are many ways to achieve this. This is a challenging technology. From the perspective of the development trend of power fiber lasers, it is also required that the pump coupling device couples the pump light to the inner cladding without affecting and damaging the core of the double-clad fiber as much as possible. In the case of generation and transmission, cascade pumping is realized to achieve super-high power output. The development direction of pump coupling devices in the pump coupling technology chamber with the least impact on the fiber core. For light power synthesis devices, the goal pursued is continuous Increase the combined optical power. 3. Fiber grating technology In all fiber lasers, the current role of fiber grating is to reflect the core of the signal laser to form a resonant cavity. However, with the further development of fiber laser technology, there will be The new application poses new challenges to the production technology of fiber gratings, and one of the directions worth paying attention to is the production of high-quality fiber gratings on large-core multimode fibers. 4. Semiconductor pumped laser technology Semiconductor pumped Lasers are the key components of fiber lasers, which are vital to the reliability, life and production cost of fiber lasers. The development of a single wide light-emitting region and long-life semiconductor pump Lasers have become a trend of semiconductor pump lasers for fiber lasers. Continuously increasing the output power of a single laser, continuously reducing costs, and further improving reliability are the key points. Among them, improving and innovating the packaging structure should be the core work, because the current packaging cost is limited. The proportion is still very high. 5. Fiber laser machine technology. The whole machine design and production of all fiber lasers has more knowledge, content, technology, craftsmanship and experience. It is the core and most critical technology for the design and production of all fiber lasers, especially in the new large The development history of power all-fiber lasers is still quite short today, and there is still a lot of groundbreaking work to be done. The design and production of the whole machine of the all-fiber laser requires not only a reasonable design for the application, but also the responsibility of improving and innovating the whole machine structure and scheme. At present, all manufacturers who design and manufacture fiber laser machines all over the world have invested a lot in innovation. The application of the above five technologies makes the fiber laser has a very unique advantage, so that the fiber laser cutting machine reflects its outstanding cutting performance. In the future laser cutting machine market, Wuhan High Energy Laser will vigorously develop and innovate more practical fiber laser cutting machines, which are suitable for more different industries and contribute their own strength to the economic development of society.
