High power density of fiber laser cutting machine

Under specific pumping conditions, all these working media can achieve 'population inversion' and produce a certain wavelength of laser for fiber laser cutting machine. HYG D fiber laser marking machine adopts more advanced pulses in the world today. fiber-optic laser. Fiber lasers are developed on the basis of fiber amplifiers. Fiber amplifiers use fibers doped with rare-earth elements, plus an appropriate feedback mechanism to form fiber lasers. Fibers doped with rare-earth elements act as The gain medium of the fiber laser. There is a very thin fiber core in the fiber laser. Due to the action of the external pump light, it is easy to form a high power density in the fiber, which causes the population inversion of the energy level of the laser working material. The fiber grating is used as a tree-weighted cladding fiber made by a special process for fiber excitation. The multimode pump light is introduced from the fiber fork to correct a small rare-earth element doped (such as mirror) in the tree-weighted fiber. Mode fiber core pumping. When the pump light traverses the single-mode fiber core every time, the atoms of the rare earth element are pumped to the upper energy level, and then spontaneous emission light is generated through the transition. The frequency selection effect of the fiber grating arranged in the fiber is specified The spontaneous emission light of the wavelength is amplified by the oscillation and finally produces the laser output. If the cladding fiber material is doped with different rare earth elements, such as erbium, thulium, zirconium, mirrors and other different rare earth elements, the fiber laser will have a variety of different laser wavelength output.

The fiber laser cutting machine uses cladding and parallel pump technology to couple multiple laser diodes to the cladding fiber at the same time to obtain higher power laser output. The basic principle is shown in the figure: How to buy fiber laser cutting machine content source network, collected by 'Machinery Exhibition (110 thousand m', more than 1100 exhibitors, over 100,000 visitors)'! More cnc processing centers, cars Milling and drilling machines. Wire cutting, CNC tool tools, grinding wheels, automation, digital unmanned factory, precision measurement, 3D printing, laser cutting, laser welding, sheet metal stamping and bending, precision parts processing, etc. are displayed at the machine exhibition. There are many prototypes and mass productions. How to complete customer orders with quality and quantity, maintain corporate reputation, and enhance corporate competitiveness is also an arduous task for every operator. Therefore, purchasing processing equipment with stable performance is the prerequisite and Basically, try to choose a high market share. Brands with a sound after-sales service system, a large number of after-sales service outlets and long-term market inspections, can’t just buy low-quality products without after-sales service just because of low prices. Production has a huge impact. 6, After-sales service The after-sales service of each manufacturer is very different, and the warranty period is also uneven.
