Abstract: According to an embodiment of a laser cutting nozzle where a shroud can move along the central axis of the laser cutting nozzle in the axial direction. The shroud is designed to mate with interior walls along a nozzle cavity extending from a cavity base of the nozzle body. The exterior side walls of the shroud and interior side walls of a cavity of the nozzle body are multi-sided (e.g., in complementary polygonal shapes). Shroud rotation about the central axis of the laser cutting nozzle is limited or prevented by an interlocking arrangement between the exterior side walls of the shroud and the interior side walls of the nozzle body.
