Scanning pulse delays in multi-pulse non-linear optical spectroscopy experiments is a major contributor to lengthy data acquisition. Using large steps for the scan can significantly speed up the experiment. However, an improper choice of step length can cause distortions to the resulting spectra, especially if the light scattered on the sample is mixed into the signal. In this work, we identify potential sources of such distortions and suggest appropriate countermeasures to avoid them while maintaining a faster data collection.

二维电子光谱中相干时间欠采样和散射光之间的相互作用

多脉冲非线性光谱实验中的扫描脉冲延迟是导致数据采集时间过长的主要因素。使用大步长进行扫描可以显着加快实验速度。但是，步长选择不当会导致光谱失真，尤其是在样品上散射的光混合到信号中的情况下。在这项工作中，我们确定了这种扭曲的潜在来源，并提出了适当的对策来避免它们，同时保持更快的数据收集。
