Abstract

We develop a mathematically simple yet accurate model for the single-pulse non-resonant impulsive alignment of thermal ensembles of linear molecules. We find that our molecular alignment model not only provides a simplification for analytical and numerical calculations, but also establishes intuitive connections between system parameters, such as gas temperature and laser pulse intensity, and the resulting shape of the temporal molecular alignment.
