原子内壳层X射线laser的光学控制

Optical control of an atomic inner-shell x-ray laser

Gábor Darvasi, Christoph H. Keitel, Christian Buth

摘要:

X射线自由电子激光器通过实现具有前所未有强度的飞秒脉冲,对X射线科学产生了巨大影响。然而,目前由自放大自发发射(SASE)原理操作的设施具有许多缺点,即,它们的辐射具有混乱的脉冲轮廓和短的相干时间。提出了一种基于飞秒激光器的原子内壳层X射线激光器(XRL)方案,该方案能够产生时间和空间相干的亚飞秒脉冲,并由飞秒激光器控制和同步。我们设想,这样的XRL将允许许多应用,如核量子光学和原子,分子和凝聚态的超快量子动力学的研究。

英文摘要:

X-ray free-electron lasers have had an enormous impact on x-ray science by achieving femtosecond pulses with unprecedented intensities. However, present-day facilities operating by the self-amplified spontaneous emission (SASE) principle have a number of shortcomings, namely, their radiation has a chaotic pulse profile and short coherence times. We put forward a scheme for a neon-based atomic inner-shell x-ray laser (XRL) which produces temporally and spatially coherent subfemtosecond pulses that are controlled by and synchronized to an optical laser with femtosecond precision. We envision that such an XRL will allow for numerous applications such as nuclear quantum optics and the study of ultrafast quantum dynamics of atoms, molecules, and condensed matter.
