Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber lasers, and in particular relates to an optical fiber plate and a laser and a laser processing system comprising the same. Background Art

[0002] When transmitting light, optical fibers absorb and convert it into heat. As heat accumulates, the temperature inside the fiber rises, damaging the high-power fiber and internal components, rendering the laser inoperable. To improve the fiber's heat dissipation efficiency and maintain high laser stability and performance, the fiber coil is typically placed on a pre-machined mechanical heat sink. Cooling and heat dissipation are achieved through contact heat conduction between the heat sink and the fiber. The heat sink is machined with a fiber groove, into which the fiber coil is wound, and water-cooling is achieved through contact between the fiber and the bottom and sides of the water-cooling device.

[0003] Existing fiber optic discs and cooling plates are manufactured as a single piece. The fiber optic disc that secures the optical fiber is typically machined onto the surface of the cooling plate. The fiber optic disc is essentially a groove formed on the cooling plate. However, the cooling plate and fiber optic disc are typically machined as a single piece. The cooling plate is typically made of hard metal, and the grooves are typically machined, such as by turning on a milling machine. This makes the process difficult and expensive, and the subsequent maintenance process is time-consuming, lengthy, and complex. Furthermore, conventional structures also cause the optical fiber to float, which increases the distance between the optical fiber and the cooling source, reduces heat dissipation efficiency, and affects the performance and stability of the optical fiber. Figure 1 , an integrated fiber optic plate, the cooling plate 1 of which is machined with a fiber optic groove 5, which is used to accommodate the optical fiber 3. During assembly, the optical fiber 3 is first placed in the fiber optic groove 5, and then the thermal conductive gel 4 is injected into the fiber optic groove 5. At this time, the optical fiber 3 will float up due to the injection of the thermal conductive gel to generate a floating height d. In this way, the optical fiber 3 will be away from the cooling channel in the cooling plate 1 (not shown), thereby reducing the heat dissipation efficiency relative to the heat dissipation efficiency when it is not floated.
