PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a processing device of high output.SOLUTION: The processing device comprises: a laser device including a single mode optical fiber laser that outputs laser light of a basis mode, and a process optical fiber that is a multimode optical fiber propagating and outputting the laser light outputted from the single mode optical fiber laser; and a spatial optical system that guides the laser light outputted from the laser device to a processing target. An output-side single mode optical fiber that is positioned on an output-side final stage of the single mode optical fiber laser and the process optical fiber are fused and connected in such a manner that center axes of cores are matched with each other. In an output-side end portion of the process optical fiber, an optical connector is provided and directly connected to the spatial optical space.SELECTED DRAWING: Figure 6
