Abstract
A laser processing device comprising: an optical arrangement; wherein the optical arrangement comprises an input for receiving a laser beam; wherein the optical arrangement comprises a beam splitter that splits the laser beam into at least two partial beams; wherein the optical arrangement recombines the partial beams into a laser spot for generating an interference pattern in the laser spot; wherein a first state of the laser beam at the input generates a first interference pattern and a second state of the laser beam generates a second interference pattern; wherein the first state and the second state differ in at least one of (i) a position of the laser beam at the input and (ii) an angle of incidence of the laser beam with respect to the input; and wherein the optical arrangement is configured such that the second interference pattern continues the first interference pattern in phase.
