In this article, we report on the fabrication of periodic arrays using multibeam laser interference patterning (MLI) with both nanosecond and femtosecond lasers on hydrogel materials. Configurations involving two, four, and five laser beams were utilized being able to produce a wide range of periodic arrays.
