Population inversion in fluorescing fragments of super-excited molecules inside an air filament
Population inversion in fluorescing fragments of super-excited molecules inside an air filament |
| Fig.#cod#x0A0;4. Schematic of the excitation of a molecule by either single XUV photon absorption or by multiphoton absorption in an intense laser field with population trapped in the SES. The parent molecule is denoted by AB, where A and B could each be either an atom or a molecule. The super-excited state is denoted by AB ** . Its rapid fragmentations into various fragments via different pathways are given in the panel at the right-hand side. |
