3D Beam Reconstruction by Fluorescence Imaging
Neal Radwell, Mordjane Alissa Boukhet, Sonja Franke-Arnold
We present a technique for mapping the complete 3D spatial intensity profile of a laser beam from its fluorescence in an atomic vapour. We propagate shaped light through a rubidium…

Ultra high densities of cold atoms in a holographically controlled dark SPOT trap
Neal Radwell, Graeme Walker, Sonja Franke-Arnold
We demonstrate an atom trap geometry for 87Rb which is capable of producing ultra high atom densities. Reradiation forces, which usually limit high densities, can be avoided in dar…
