Soft X-ray recombination lasing by Li-like TiXX ion

Li-like ion scheme of recombination pumping mechanism is one of the most promisingapproaches to compact and efficiently saturated amplifier in the 'Water Window' spectral re-gion. Recently, numerous important investigations have been made in a number of famouslaboratories worldwide and considerable progresses have been made. However, someissues on the lasing mechanism have not been quite understood yet. Especially When one at-

类锂硅软X射线激光模拟

对１１６ｐｓ，功率密度为５．４×１０（１２）Ｗ／ｃｍ２的激光脉冲和硅平板靶的相互作用进行了数值模拟，得到了类锂硅离子４ｆ粒子波居数和４ｆ－３ｄ跃迁增益系数的时空变化，并与实验结果进行了比较。
