In article number 1900344, Jérémy Bert, Ilya Sh. Averbukh, Olivier Faucher, and co‐workers demonstrate a novel optical method for visualizing rapidly spinning molecules in the gas phase. The method is based on detecting the time‐dependent birefringence of the laser excited molecular gas, and it allows recording images similar to the one shown on the cover. A sequence of such images is combined into a high‐resolution molecular movie providing information on molecular orientation with a resolution of few tens of femtoseconds.

时间分辨分子成像：相干分子转子的光学成像（Laser Photonics Rev. 14（5）/ 2020）

杰里米·伯特（JérémyBert），伊利亚·舒（Ilya Sh。）Averbukh，Olivier Faucher及其同事展示了一种新颖的光学方法，用于可视化气相中快速旋转的分子。该方法基于检测激光激发的分子气体随时间变化的双折射，并且可以记录类似于封面所示的图像。一系列这样的图像被组合成高分辨率的分子电影，以数十飞秒的分辨率提供有关分子取向的信息。
