ABSTRACT:
A processing table3holding a workpiece2is accommodated in a chamber4with a gas-tight condition kept, and a liquid column W is jetted to an upper surface of this chamber4, and a processing head9that guides laser beam L to the liquid column W is secured to the upper surface of this chamber4.An oil-sealed rotary pump11and a diffusion pump12provided in parallel are connected to the chamber4, and the diffusion pump12is actuated after the actuation of the oil-sealed rotary pump11, bringing the inside of the chamber4into a vacuum state.No gas currents are generated around the liquid column W jetted from the processing head9, making it possible to prevent turbulence of the liquid column W due to turbulence of the gas currents and enabling a liquid column having a small diameter to be jetted in a stable state.
