Abstract (en)
[origin: CA3134472A1] A laser machining device (100) for producing a multiplicity of grooves in a surface (110) has an optical diffraction arrangement (102), which is designed for receiving laser radiation (104) and for then producing output radiation (106), wherein the output radiation (106) has a multiplicity of intensity maxima. An actuator arrangement (108) is provided for producing a relative movement between the output radiation (106) and the surface (110), wherein each intensity maximum produces a groove of the multiplicity of furrows.
