ABSTRACT:
A method for generating X- or EUV-radiation via laser plasma emission, in which at least one target (17) is generated in a chamber, and at least one pulsed laser beam (3) is focused on the target in the chamber. The target is generated in the form of a jet (17) of a liquid, and the laser beam (3) is focused on a spatially continuous portion of the jet (17). An apparatus for generating X- or EUV-radiation via laser plasma emission according to the method comprises a means for generating at least one laser beam (3), a chamber, a means (10) for generating at least one target (17) in the chamber, and a means (13) for focusing the laser beam (3) on the target (17) in the chamber (8). The target-generating means (10) is adapted to generate a jet (17) of a liquid. The focusing means (13) is adapted to focus the laser beam (3) on a spatially continuous portion of the jet (17).
