Possibility of constructing a far-ultraviolet laser utilizing transitions in multiply charged ions in an inhomogeneous plasma

Abstract

Heavy fermions compounds show highly unusual properties. The most striking one is probably superconductivity. Triplet superconductivity has been suggested. Here we want to suggest that singlet superconductivity is possible. We first emphasize that heavy fermions are due to quasi localized f-electrons. Thus we show that magnetic correlations are important in this heavy Fermi liquid. Even in the non magnetic case, magnetic interactions as measured for instance by the paramagnetic Curie temperature, are greater than the Kondo temperature. This point, using a Fermi liquid theory,

Theoretical Study of Laser Emission for C-Like (Ar XIII), (Ti XVII) and (Fe XXI)

“…The last three decades enormous advances in our understanding and developing high-efficiency of X-ray laser with gain [1] [2] by using the mechanism for demonstrating X-ray lasing in resonant photo pumping have been seen. The pump power needed to achieve inversion was extremely high.…”

Resonant photo-pumping x-ray-laser scheme using intense characteristic x rays for water-window radiation generation

“…At Lawrence Livermore National Laboratory, the SHIVA and NOVETT laser facilities were used to design the x-ray flash lamps for several resonant photo-pumping schemes [15,16]. At Sandia National Laboratory [17], a Saturn * kawachi.tetsuya@jaea.go.jp Z-pinch machine was used to test the heliumlike sodium 1s-4p laser pumped by the resonance line of heliumlike neon ions, which was the scheme proposed by Vinogradov et al [20]. The kryptonlike molybdenum (Mo VII) ion laser pumped by galliumlike molybdenum ions (Mo XII), proposed by Feldman et al [21], was investigated at Princeton University [18].…”

XUV and Soft X-Ray Laser Radiation from Ni-Like Au

“…Experimentally there exist in the literature some studies trying to develop high-efficiency X-ray laser with significant gain. For example Vinogradov et al and Norton et al [1,2] proposed the original mechanism for demonstrating X-ray lasing by resonant photopumping. Several authors during the past three decades [3][4][5][6][7][8] have studied this lasing mechanism experimentally and theoretically, in the hope of developing high-efficiency X-ray laser.…”
