[0004] However, in the water-guided laser processing device in the prior art, when the liquid and the laser are coupled, the coupling power is still relatively low and the total reflection efficiency of the laser is relatively low, so that the output power of the laser is low, so the processing depth of the laser is still low. Can not meet the needs of some occasions

Description
technical field [0001] The application relates to a water-conducting laser processing device and a processing system, belonging to the technical field of laser processing. Background technique [0002] Water-guided laser processing technology is a technology in which a fine water jet guides the laser for processing. Due to the difference in the refractive index of the laser in water and in the air, the laser propagating in the water is totally reflected at the interface between the water beam and the air and is limited to Inside the water beam, the water beam acts as a light-guiding fiber. [0003] At this stage, the patent CN108262556A discloses a high-power coupled water-conducting laser processing device, which includes a liquid chamber, a window lens, a liquid chamber including a focusing lens, a support structure and a liquid vena contracta conduction device, and a liquid vena contracta conduction device The inner wall of the laser is coated with a total reflection coa...
