高次谐波产生（HHG）是一种非线性光学过程，通常被解释为原子或分子在强激光场作用下电离，然后在极紫外光子辐射下复合的过程。我们研究了红外和极紫外光场联合作用于具有两个基本态的系统的高次谐波，激发态是束缚态或共振态。我们报告的HHG峰的位置相比，从红外场的HHG光谱的位移和峰分裂取决于拉比振荡的存在。
High-order harmonic generation (HHG) is a nonlinear optical process usually interpreted as a sequence of ionization of an atom or molecule by a strong laser field and the following recombination under emission of an extreme ultraviolet photon. We investigate HHG for combined infrared and extreme ultraviolet fields acting on a system possessing two essential states, with the excited state being either a bound state or a resonance. We report shifts of the HHG peak positions compared to the HHG spectrum from an infrared field only and a peak splitting depending on the presence of Rabi oscillations.
