可调谐阿秒瞬态吸收光谱是研究和控制连续介质中自电离动力学的理想工具。我们研究了氩的亮自离态和暗自离态之间的近共振双光子耦合,这种耦合导致了奥特勒-汤斯类相互作用,形成纠缠的光物质态或极化子。我们观察到与中间暗态的单光子耦合在这种相互作用中起着重要作用,导致形成多个极化分支,其能量表现为避免交叉作为修饰激光频率的函数。我们的实验测量和理论基本态模拟显示出良好的一致性,并揭示了修整脉冲的延迟,频率和强度如何控制自电离极化多态的性质。这些结果为利用光场量子控制自电离态提供了新的途径。
Tunable attosecond transient absorption spectroscopy is an ideal tool for studying and manipulating autoionization dynamics in the continuum. We investigate near-resonant two-photon couplings between the brightand darkautoionizing states of argon that lead to Autler-Townes-like interactions, forming entangled light-matter states or polaritons. We observe that one-photon couplings with intermediate dark states play an important role in this interaction, leading to the formation of multiple polaritonic branches whose energies exhibit avoided crossings as a function of the dressing-laser frequency. Our experimental measurements and theoretical essential-state simulations show good agreement and reveal how the delay, frequency, and intensity of the dressing pulse govern the properties of autoionizing polariton multiplets. These results demonstrate new pathways for quantum control of autoionizing states with optical fields.
