Abstract
A laser cutting head associable to a machine tool comprises a collimating group to collimate a laser beam coming from a laser emitting apparatus, a focusing group to focus in a focal point the laser beam collimated, an optical element to receive said laser beam focused and reflect a focused first portion thereof, and a wavefront sensor to receive said focused first portion of the laser beam, perform a phase measurement of a wavefront of said focused first portion, obtain a reconstructed wavefront on the basis of the phase measurement and send the reconstructed wavefront to an electronic processor; the electronic processor compares the reconstructed wavefront and a reference wavefront, determines one or more optical aberrations to which the laser beam is subjected, reduces such optical aberrations and changes said focal point.
