【摘要】 我们以Hg蒸气为非线性光学介质、用毛细列阵做输出窗口，成功地得到了波长小于100nm的可调谐XUV相干辐射。本文深入研究了毛细列阵作为输出窗产生XUV相干辐射的可行性；以Hg的61D、63D为共振能级的双光子共振三次谐波过程产生XUV可调谐相干辐射的机制；以及影响XUV光产生效率的因素，诸如光学斯塔克效应，介质对泵光及产生光的吸收，不同非线性过程的相互竞争等，并在此基础上提出了改进方案。更多还原

【Abstract】 The generation of coherent XUV radiation by two-photon resonant four-wave sum-mixing has been studied. The capillary array is used as the exit-window,and an 6 3D for the two-photon resonant enhanced levels. The efficiency of the generation, optical Stark effect, and the competition between different nonlinear optical processes have also been discussed in this paper.更多还原
