Abstract: To cut paper, timber, fabric etc., with a laser beam, a jet of air (or other gas which is inert in the process) carrying an atomized stream of a liquid coolant is directed on to the moving region of the workpiece at which the laser beam is concentrated. This reduces the spread of charring or tar deposit from the cut along the surfaces of the workpiece.

Abstract: A workpiece is cut or gouged by moving a concentrated laser beam along its surface and directing on to the moving region of the workpiece, at which the laser beam is concentrated, a gas which produces an exothermic reaction at the heated workpiece and sweeps away the products of combustion. In apparatus for supplying a gas to a workpiece the gas is led into a tube and nozzle surrounding the laser beam and is directed at the workpiece through the same nozzle.
