Abstract: The mechanism of remote cutting of steel plates by radiation of a high-power repetitively pulsed CO₂ laser is theoretically studied. The models of melt removal by the gravity force and the recoil pressure of material vapour are proposed and the sufficient conditions for the initiation of cutting are determined. A numerical model of a thermally thin plate was employed to describe the cutting for large focal spots.
