摘要：

We demonstrate lasing on the nickel-like 3d(9) 4f(1) P-1 --> 3d(9) 4d(1) P-1 x-ray laser line in Zr (Z = 40), Nb (Z = 41), and Mo (Z = 42) and present measured wavelengths for these ions as well as predicted values for ions from Z = 36 to 54. Lasing on this line was first predicted two years ago and has now been achieved. Unlike the usual collisional excitation laser, this line lases because radiation trapping allows a large radiation field to build up on the 3d(10) S-1(0) --> 3d(9) 4f(1) P-1 resonance line and populate the 4f upper laser state by the self-photopumping process. For Ni-like Mo again of 13 cm(-1) is measured on this transition at 226 Angstrom for targets up to 1 cm long. [S1050-2947(99)51010-X].
