The fiber Laser Marking Machine uses optical fiber as gain medium and has a large surface area/volume ratio, which makes it have very good heat dissipation performance. Therefore, even if a very high-power fiber laser is used, the gain medium will not be damaged by heat. No special heat dissipation measures are required for the gain medium. However, other kinds of lasers and heat dissipation problems of the gain medium need to be considered. Therefore, this feature is unique to fiber lasers.
Excellent dual waveguide restriction mechanism
High-power all-fiber lasers use double-clad active fiber. This double-layer fiber is a dual-waveguide structure. High-power multimode pump light is confined to transmission in a relatively large-diameter inner cladding, which is inexpensive and uses high power. The multi-mode pumping light provides the condition that the signal laser is generated and transmitted in a small-diameter core having a circular symmetric waveguide structure, and the signal laser can obtain an ideal beam quality under the constraint of a small-core core waveguide. The extremely small spot diameter of the exit light is an important feature of all-fiber lasers. Among the high-power lasers, no one laser can surpass it. Excellent beam quality and extremely small spot diameter in laser application are of great importance in laser applications, enabling the optical system of subsequent applications to be simpler, smaller in size, longer working distance, smaller laser spot size, and more efficient work. High, deeper processing, better processing quality, and more.
