摘要
This document discloses a laser nozzle (1) for gas-assisted cutting by means of a laser beam (6), comprising an inlet (12), an outlet (13), and a channel (14) extending between the inlet (12) and outlet (13) for the laser beam (6) and cutting gas. The channel (14) has a central axis (Z). The channel (14) has a first portion (141) with an inwardly facing surface (112). The laser nozzle comprises a substantially helical blade (16) which extends radially inwardly from the inwardly facing surface (112) and extends over at least 300 degrees around the central axis (Z) and along the inwardly facing surface. The document also discloses an inset for a laser nozzle, a laser cutting device and methods of laser cutting.
