| 英文摘要 | This paper is engaged in the study of the short-wavelength X-ray laser physics. The main creative achievements are summarized as below: 1)The lasing by Lithium-like Ti ion 4f-3d transition at 4.68nm is demonstrated experimentally; 2)The plasma parameters for the optimized gain region for recombination X-ray lasing are derived analytically; 3)The spatial characteristics of the effect of pre-pulse on the on-axis X-ray emission of line-shaped plasma is studied experimentally; 4)The correlation between the gain-coefficient decreasing over long plasma medium for recombination soft-x-ray laser and the change of average electron density in amplification region is found; 5)A new target geometry for the possible enhancing of gain coefficient of recombination X-ray laser is successfully designed; 6)The spectral imaging characteristics of the variable line spcing concave grating with a spherical surface are theoretically and experimentally studied; 7)The imaging characteristics of the graze-incidence 1-D imaging optics are analyzed by simulation code and experiments. |
