  1. 11. Microwave dressing of a trapped strontium Rydberg ion

    Author : Fabian Pokorny; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : Trapped Rydberg ions are a novel platform for quantum technologies, envisaged to combine the excellent control of trapped ions with the strong interactions found in neutral Rydberg atom systems. While in recent years trapped ions have been coherently excited to Rydberg states and were shown to be stable in the trapping field, strongly interacting trapped Rydberg ions have yet to be realized.

  2. 12. Experimental Techniques for Studies in Atomic & Molecular Physics

    Author : Filip Heijkenskjöld; Jan-Erik Rubensson; Peder Royen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; fast ion beam laser spectroscopy; time of flight photoelectron photoelectron coincidence; hyperfine structure; Rabi oscillation; Physics; Fysik;

    Abstract : This thesis is based on a selection of six different experimental techniques used for studies in atomic and molecular physics. The techniques analysed in the thesis are compared to find similarities in strategies and ways to avoid sources of error.Paper 1 deals with collision based spectroscopy with 60 keV Xe6+ ions on sodium and argon gas targets.

  3. 13. Time Resolved Laser Spectroscopy of Rydberg States in Group IIIA and IIIA Elements

    Author : Göran Jönsson; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this work radiative properties of neutral elements with one or two electrons outside closed subshells have been investigated. Using laser techniques in connection with atomic beams selective excitation of Rydberg states was performed. Most of the studied states were populated with two-step excitation. READ MORE

  4. 14. Characterisation and Applications of Ultrashort Extreme Ultraviolet Pulses

    Author : Johan Norin; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ultrashort pulses; pulse characterisation; sidebands; interferometry; Atom- och molekylärfysik; acetylene; Atomic and molecular physics; High-order harmonics; XUV; Fysicumarkivet A:2002:Norin;

    Abstract : When a strong laser field interacts with free atoms, harmonics up to very high orders are created. This extreme ultraviolet (XUV) radiation has interesting properties, such as spatial and temporal coherence, short pulse duration and high brightness. This thesis concentrates on the temporal aspects of this radiation. READ MORE

  5. 15. Time-resolved laser spectroscopic studies of atoms, ions and Molecules

    Author : Zhongshan Li; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2000:Li;

    Abstract : Time-resolved laser spectroscopy has been performed to study the radiative properties of various microscopic systems. Using Laser-Induced Fluorescence (LIF) techniques, natural radiative lifetimes have been studied not only in neutral B, S, Ge, Ce, Pb, and in singly ionized V, Fe, Zr, Mo, La, Ce, Eu, Gd and Yb, but also in doubly ionized La, Ce, Pr, Eu, Er, Gd, Tm, Lu, and W.
