Single-Shot, Space- and Time-Resolved Measurement of Rotational Wavepacket Revivals in H{sub}2 and D{sub}2

摘要

Femtosecond laser induced alignment and periodic recurrences of room temperature hydrogen and deuterium molecules are measured in a single shot for the first time, using single-shot supercontinuum spectral interferometry (SSSI). The measurements are also performed in oxygen and some other common linear molecular gases. Employing time-dependent first order perturbation theory, an analytical model of rotational wavepacket revivals is derived, which shows good agreement with the experiment.
