Characterization of high intensity Ni-like X-ray lasers and their application experiment

At the Institute of Laser Engineering, Osaka University, we have obtained N i-like. x-ray lasers of various atomic number elements, including many shor ter wavelength Ni-like lasing lines around 5nm. The saturated amplification of Ni-like Ag lasing line at the wavelength of 13.9nm have been observed. Using these x-ray lasers, we are preparing the application experiments such as probing a laser-produced plasma with an x-ray laser interferometer.
