Abstract

The laser machining device comprises a beam splitter (1) which has a pyramid mirror. The beam splitter splits up a central laser beam into several laser beams. Each laser part beam is provided with a focusing mirror (5) which is slidably arranged on the radial axis of the optical ray splitter.
