| 中文摘要 | Calculations of the modal photon densities and gain in a photopumped Cl XVII-Se XXXII X-ray laser are presented. In this paper we undertake a realistic simulation of the generation of both Cl and Se plasmas, using a high-power optical laser, which includes radiation from both Ly-alpha fine-structure components of H-like Cl pumping the 2p(3/2)-5d(5/2) transition in Li-like Se. The calculations are performed in two dimensions in a realistic geometry taking into account plasma gradients. This gives information about the spatial extent and time evolution of X-ray lasing gain on the 5-4 transitions (39.5 Angstrom) in Li-like Se. We find that gain (about 200 cm(-1)) is expected only when the optical laser includes a pre-pulse. Calculations show that the absorption of pumping radiation in the pumped plasma can reduce the gain by 20%. Time-dependent calculations have shown that the gain is reduced by 30% in comparison to the steady-state calculations. The effect of the spectral profile and self-radiation of 5d(5/2)-2p(3/2) transition in Li-like Se reduces the gain by about 2%. (C) 2003 Elsevier Ltd. All rights reserved. |
