Manipulation and Control of Molecular Beams
Chemical Reviews, 2012 A study was conducted to demonstrate the manipulation of molecular beams with electric and magnetic fields. Seeded pulsed supersonic expansions were employed to conduct the investigations. The conservative forces exerted further downstream by the electric and magnetic fields enabled the researchers to manipulate and control the shape and the position ...

Multi-beam vortex generation induced by the non-linear optical anisotropy of graphene [PDF]
EPJ Web of Conferences, 2022 We analyse the high harmonic emission from single-layer graphene driven by infrared vector beams. We demonstrate that graphene’s anisotropy offers a privileged scenario to explore non-trivial light spin-orbit couplings, which substantially extends the ...

A cold and slow molecular beam [PDF]
Physical Chemistry Chemical Physics, 2011 Employing a two-stage cryogenic buffer gas cell, we produce a cold, hydrodynamically extracted beam of calcium monohydride molecules with a near effusive velocity distribution. Beam dynamics, thermalization and slowing are studied using laser spectroscopy.
