EUV Sources Track Molecular Dissociation in Tandem
HEIDELBERG, Germany, Dec. 12, 2023 — Reportedly for the first time, scientists have combined a broadband extreme-ultraviolet (EUV) probe pulse from high-order harmonic generation (HHG) with a free-electron laser (FEL) pump pulse to observe photodissociation pathways leading to fragments in different quantum states. The team, led by Christian Ott at the Max-Planck-Institut für Kernphysik, temporally resolved a quantum mechanical dissociation mechanism of a specific O2+ state into two competing channels by measuring the
Lasers, Spectroscopy, and OCT Cut Bone Safely
