Abstract

Most issues related to laser processing, such as self-focusing or filamentation, have been resolved but rely on complex and costly methods that cannot be used simultaneously. The new method developed by Jérôme Lapointe not only addresses several important laser processing challenges simultaneously but is also simple and costs less than $1. The technique is driven by the addition of a filter in front of the lens to generate two thin laser beams focalized. Besides potentially making laser surgeries more exact, the new technique could reduce errors when cutting electronic microchips.
