我们报告了使用外部幅度和相位控制的超短极紫外光脉冲的生成、压缩和传输。首先通过将精心选择强度的红外激光聚焦到含有氩原子的气室中来产生宽带谐波辐射。然后，发射的光穿过硬孔径和薄铝滤光片，该滤光片选择 30-eV 光子能量周围的 30-eV 带宽并同步所有组件，从而形成一系列几乎受傅里叶变换限制的单周期 170 阿秒脉冲。我们的实验展示了一种合成和控制阿秒波形的实用方法。
We report the generation, compression, and delivery on target of ultrashort extreme-ultraviolet light pulses using external amplitude and phase control. Broadband harmonic radiation is first generated by focusing an infrared laser with a carefully chosen intensity into a gas cell containing argon atoms. The emitted light then goes through a hard aperture and a thin aluminum filter that selects a 30-eV bandwidth around a 30-eV photon energy and synchronizes all of the components, thereby enabling the formation of a train of almost Fourier-transform-limited single-cycle 170 attosecond pulses. Our experiment demonstrates a practical method for synthesizing and controlling attosecond waveforms.
