Laser cooling of dense atomic gases by collisional redistribution of radiation and spectroscopy of molecular dimers in a dense buffer gas environment
Anne Saß, Ralf Forge, Stavros Christopoulos +3
We study laser cooling of atomic gases by collisional redistribution of fluorescence. In a high pressure buffer gas regime, frequent collisions perturb the energy levels of alkali…
Kennard-Stepanov relation connecting absorption and emission spectra in an atomic gas
Peter Moroshkin, Lars Weller, Anne Sass +2
The Kennard-Stepanov relation describes a thermodynamic, Boltzmann-type scaling between the absorption and emission spectral profiles of an absorber, which applies in many liquid s…
Towards redistribution laser cooling of molecular gases: Production of candidate molecules SrH by laser ablation
Philipp Simon, Peter Moroshkin, Lars Weller +2
Laser cooling by collisional redistribution of radiation has been successfully applied in the past for cooling dense atomic gases. Here we report on progress of work aiming at the…
Laser cooling of a potassium-argon gas mixture using collisional redistribution of radiation
Anne Saß, Ulrich Vogl, Martin Weitz
We study laser cooling of atomic gases by collisional redistribution, a technique applicable to ultradense atomic ensembles at a pressure of a few hundred bar. Frequent collisions…
Light Confinement by a Cylindric Metallic Waveguide in Dense Buffer Gas Environment
Ulrich Vogl, Anne Saß, Frank Vewinger +4
We report on the implementation of metallic microtubes in a system of rubidium vapour at 230\,bar of argon buffer gas. The high buffer gas pressure leads to a widely pressure broad…
