我们增强了极紫外（XUV）谐波约90 eV的He使用真空紫外谐波的组合，产生在一个毛细管，和强红外（IR）激光脉冲。在IR输入能量或He目标的配置没有变化的情况下，两个场的共线聚焦组合改变了光谱特性，并且与仅用IR场产生的那些相比增加了XUV谐波的产率。
We have enhanced extreme ultraviolet (XUV) harmonics around 90 eV in He using a combination of vacuum ultraviolet harmonics, generated in a Xe capillary, and the strong infrared (IR) laser pulse. With no changes in the IR input energy or the configuration of the He target, the collinearly focused combination of the two fields changed the spectral properties and increased the yield of the XUV harmonics compared to those generated with the IR field alone.
