论文摘要
在这项工作中，我们提出了一个假设，即原子或分子对电磁辐射的脉冲的光谱响应具有快速上升或下降的前部的脉冲，将包含一条唯一的发射线，该发射线位于光学电子的自然振荡频率附近。在光学电子辐射能量损失时，这种“ ping”光谱线的发射将存在。对于更快的升高或下降的脉冲，“ ping”光谱线的幅度将更高。使用我们先前开发的模型的模拟证实了“ ping”光谱响应的存在。如果经过实验确认，这项工作可能会导致新的高灵敏度和高信号与噪声比率对抗检测技术，一种新型的激光雷达，以及其他未知的应用。
In this work we present a hypothesis that spectral response of atoms or molecules to a pulse of electromagnetic radiation with fast rising or falling fronts would contain a unique emission line that is located approximately near the frequency of the natural oscillations of optical electron. The emission of this "pinging" spectral line would exist during the time that is determined by the time of radiative energy loss by the optical electron. The amplitude of the "pinging" spectral line would be higher for the pulses with faster raising or falling fronts. The simulations using our previously developed model confirmed existence of the "pinging" spectral response. If experimentally confirmed, this work could lead to a new high sensitivity and high signal to noise ratio stand-off detection techniques, a new type of LIDAR, and to other yet unknown applications.
