【摘要】 借助在X光波段高次谐波辐射谱测量过程中 ,根据单色仪光栅分光的作用 ,产生的 2 3级次 (34 5 6nm)谐波谱的二级次谱 (6 9 1 3nm)的出现与否 ,判断了实验获得高次谐波谱的截止波长 ;从而根据高次谐波的理论 ,判断了强激光场与物质相互作用时 ,激励产生X光谱的有效功率密度为 1 0 0 7× 1 0 1 4 W /cm2 ,此时获得最大光子能量为32 81 7eV。它的准确判断和测量是研究实验获得谱线的来源和强度的基础数据更多还原

【Abstract】 In this paper, based on the dispersion of grating in monochromator, the cutoff wavelength of getting harmonics is judged on the appearance of 2 nd spectrum (wavelength of 69.13 nm) of the 23 rd high order harmonic (wavelength of 34.56 nm); Accordingly, the efficiency laser intensity of producing X spectrum is estimated in virtue of the theory of high harmonic which is 1.007×10 14 W/cm 2 and the most photon energy is 32.817 eV, which are the basic data of studying the origin and intensity of the spectrum in the experiment.更多还原
