| Research Abstract |
In this study, we have developed novel ultrafast laser microwelding system that can adjust the focal point position according to the height of the interface of two substrates to be welded in real time by applying autofocus system to conventional ultrafast laser microwelding system. With the present system, because it is possible to melt only the interface, the establishment of the sophisticated welding technique in terms of stability, reliability, and quality properties is possible. Further the autofocus system, which is constructed in this study, is element technology in the industrial processing field. Thus the autofocus system can apply in microprocessing such as hole drilling, grooving, and three-dimensional microprocessing.
