论文摘要
THZ场通过谐振偶极 - 场相互作用诱导气相分子的方向。然而，由于高THZ领域幅度的实际短缺，取向程度仍然受到严重限制。在本文中，我们在实验上展示了一种一致的附近IR和THZ激发方案，该方案在室温气体集合中提供了显着增加的方向。实验结果得到了理论模拟的支持，并提出了有关该方案中涉及的多个相干过渡途径的详细讨论。
THz fields induce orientation in gas phase molecules via resonant dipole-field interaction. The degree of orientation however remains severely limited due to the practical shortage of high THz-field amplitudes. In this paper, we experimentally demonstrate a concerted Near-IR and THz excitation scheme that provides significant increase in the degree of orientation at room temperature gas ensembles. The experimental results are supported by theoretical simulations and a detailed discussion of the multiple coherent transition pathways involved in the scheme is presented.
