An apparatus for creating a hole in solid sheet material (1) by laser beam irradiation is described comprising a source of laser radiation; a focusing apparatus (11) for impinging a beam of laser radiation from the source onto a surface of solid sheet material (1) in which holes are to be formed in use; and a holding device (7) for holding said solid sheet material (1); wherein the holding device (7) is structured to hold the sheet material (1) in use in an arcuate configuration. A method of creating a hole in solid sheet material making use of such an arcuate configuration is also described. |
