Lasing in Ne-like S and other new developments in capillary discharge ultrashort wavelength lasers
We report our most recent progress in the development of capillary discharge soft x-ray lasers. This includes the first observation of discharge-pumped ultrashort wavelength lasing in a material that is solid at room temperature (S), and preliminary results of discharges in Ca. Excitation by a capil...
