利用泵浦-探测实验结合分子动力学模拟研究了掺氦纳米液滴强场电离产生的双组分纳米等离子体。高产量的氦离子和显着的共振结构中的泵-探测瞬态液滴大小依赖揭示了掺杂剂诱导的氦纳米等离子体的演变与积极的作用，他壳在随后的动态。的泵浦探测动力学解释在强内电离的泵浦脉冲和共振加热的探测脉冲，控制通过电子-离子复合的挫折检测到的最终电荷状态。
Two-component nanoplasmas generated by strong-field ionization of doped helium nanodroplets are studied in a pump–probe experiment using few-cycle laser pulses in combination with molecular dynamics simulations. High yields of helium ions and a pronounced resonance structure in the pump–probe transients which is droplet size dependent reveal the evolution of the dopant-induced helium nanoplasma with an active role for He shells in the ensuing dynamics. The pump–probe dynamics is interpreted in terms of strong inner ionization by the pump pulse and resonant heating by the probe pulse which controls the final charge states detected via the frustration of electron–ion recombination.
