Abstract
Activity of our laboratory in the field of pulsed high-current proximity-wall-stabilised discharges - media for XUV/soft X-ray generation and amplification (XUV/soft X-ray lasing), and our effort to demonstrate lasing of discharge-based sources at the wavelength <15 nm are described. While lasing on the wavelength of 46,9 nm (Ne-like Ar ions) is in capillary discharge routinely achieved (due to excitation pumping scheme), lasing on the wavelength below 15 nm either has been demonstrated in laser-created plasma in Ne-/Ni-like ions of metal vapours (also due to excitation pumping scheme) or has been predicted for H-like N ions (recombination pumping scheme). For the excitation pumping of metal vapours a wire exploding in water locally compressed by focused shock wave is being prepared. The recombination pumping of N is examined in the capillary discharge geometry known from the former experiments with Ar, but at higher discharge currents (>60 kA).
