Аннотация:A soft-x-ray optical system based on multilayer mirrors was designed and fabricated for the production of magnified images of micro-objects with a spatial resolution of ,0.2 mm at a wavelength l ̄ 20 nm. The system consists of a laser-produced plasma source, a condenser mirror, a 203 Schwarzschild objective, a filter set, and a detector. The quality of the x-ray optics and the precision of the system adjustment enabled us to achieve, for the first time to our knowledge, ,0.2-mm resolution using the full aperture (numerical aperture 0.2) of the objective and a single shot of a frequency-doubled Nd laser (pulse energy ,0.5 J, pulse duration ,1.5 ns).
