Lasers typically produce a Gaussian beam where intensity is greatest in the center and tails off at the edges. In this video, ULRIKE FUCHS explains how a laser beam profile can be transformed into something more effective for material processing.
*
Drawing on insights from phase shifting microscopy, Fuchs shows how a phase plate can be used to change the phase distribution of an incoming Gaussian beam before it is focused.
*
Along with making existing processes faster, more efficient and more precise, Fuchs’s work reveals potential for exciting new applications for laser technology going forward.
