Abstract
Laser nozzle usable for laser cutting, especially with a fiber or disk laser, comprising: a nozzle body comprising an axial housing passing axially through the nozzle body and comprising a first output orifice located in the front side of the nozzle body; a movable element able to move in translation in the axial housing in the direction of the first output orifice under the effect of a gas pressure acting on the movable element; and an elastic element arranged in the axial housing, between the nozzle body and the movable element, the elastic element exercising an elastic return force on the movable element tending to oppose the translation movement in the axial housing in the direction of the first output orifice.
