Title: Self-photopumped x-ray lasers from elements in the Ne-like and Ni-like ionization state

In this paper, we report on experiments on the self-photopumped 3d 1P 1→3p 1P 1 and 4f 1P 1→4d 1P 1 laser transitions in Ne-like and Ni-like ions, respectively. Lasing on the self-photopumped laser line has been observed for the first time for a number of elements including Ne-like V, Cr, Fe, and Co as well as Ni-like Ru and Pd. We have investigated the lasing process by varying the prepulse delay, which shows a shift of the optimum main pulse to second prepulse delays towards lower values with higher atomic number Z. Time-resolved measurements showed that self-photopumped and monopole collision-pumped lasing emission occurs essentially simultaneously. Finally, accurate wavelength measurements and calculations are shown to be in excellent agreement.
