We have proposed and demonstrated a novel approach for generating high-energy extreme-ultraviolet (XUV) continuum radiation. When a two-color laser field consisting of a sub-10-fs fundamental and its parallel-polarized second harmonic was applied to high-order harmonic generation in argon, a continuum spectrum centered at 30 nm was successfully obtained with an energy as high as 10 nJ. This broadband emission indicates the possibility of generating intense single attosecond pulses in the XUV region.
我们提出并展示了一种产生高能极紫外（XUV）连续辐射的新方法。当由亚10飞秒基频光及其平行偏振二次谐波组成的双色激光场应用于氩气中的高次谐波产生时，成功获得了中心波长为30纳米、能量高达10纳焦的连续谱。这种宽带发射表明了在极紫外区域产生高强度单个阿秒脉冲的可能性。
