论文摘要
迄今为止，时间分辨的研究依赖于在化学或生物离子或分子中迅速触发了光诱导的动态，然后用快速移动的光子或电子束在短时间内跨研究样品进行探测。因此，信号的时间分辨率主要由泵和探针脉冲的脉冲持续时间设定。在本文中，我们提出了一种针对此问题的方法，该方法具有一致地达到数量级分辨率的潜力，而不是激光技术或电子束压缩方法的时间分辨率。我们提出的方法依赖于将样本加速到高速上以实现相对时间扩张。探测时间删除的样本将打开以前无法访问的时间分辨率域。
Time-resolved studies have so far relied on rapidly triggering a photo-induced dynamic in chemical or biological ions or molecules and subsequently probing them with a beam of fast moving photons or electrons that crosses the studied samples in a short period of time. Hence, the time resolution of the signal is mainly set by the pulse duration of the pump and probe pulses. In this paper we propose a different approach to this problem that has the potential to consistently achieve orders of magnitude higher time resolutions than what is possible with laser technology or electron beam compression methods. Our proposed approach relies on accelerating the sample to a high speed to achieve relativistic time dilation. Probing the time-dilated sample would open up previously inaccessible time resolution domains.
