The effect of WFI produced as a result of SMBS is used for sharp focusing on a target of a 5and 10-nsec pulse with energy of up to 20 J from a neodymium laser. The distribution of the intensity in the focal spot is estimated; 50% of the energy is contained in a circle with an area of ~2 X 10 ~5 cm2. The x-ray spectra of multiply charged Mg and Fe ions were recorded as a result of irradiation of flat targets in a vacuum.
