In this study, we explored the possibility of simultaneous multipoint joining of glass by using a spatial light modulator (SLM) to form an arbitrary number of light collection points. In the experiment, we compared the results of simultaneous multi-point joining with those of conventional multi-point joining in which a single point is scanned multiple times. As a result, in the case of simultaneous multi-point joining, the first joint trace was not affected by the later joint trace, and the joining with fewer cracks was achieved.
