2. 1. Spatial and temporal aspects of intense attosecond pulses for pump-probe experiments

   Author : Hampus Wikmark; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrafast lasers; ultrafast optics; attosecond pulses; pump-probe experiments; XUV light; XUV focusing; wavefront sensing; XUV optics; X-ray optics; Fysicumarkivet A:2019:Wikmark; ultrasnabba lasrar; attosekundspulser; pump-prob-experiment; XUV-ljus; vågfrontmätningar; XUV-optik; Röntgen-optik;

   Abstract : Nuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. READ MORE

4. 2. Temporal Aspects of High-Intensity Laser-Matter Interactions

   Author : Johan Mauritsson; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Laser technology; Relativistic Self-Focusing; High-Intensity Lasers; Attosecond Pulses; Pulse Characterization; XUV; High-Order Harmonics; Ultrashort Pulses; Laserteknik; Atom- och molekylärfysik; Atomic and molecular physics; Fysicumarkivet A:2003:Mauritsson;

   Abstract : The availability of short-pulse, high-intensity lasers has opened doors to new areas in atomic and plasma physics. The short pulses (a few femtoseconds), that are available today, enable unprecedented temporal measurements, while the high peak power accessible (several terawatts) allows physicists to study the interaction between light and relativistic plasmas.

5. 3. Spatial and temporal metrology of intense attosecond pulses

   Author : Helene Coudert-Alteirac; Atomfysik; []
   Keywords : Ultrafast optics; High-order harmonic generation; Filamentation; Attosecond; Femtosecond; Extreme ultraviolet; Wavefront measurement; Optical metrology; XUV optics; interferometry; Pump-probe; Fysicumarkivet A:2018:Coudert-Alteirac;

   Abstract : Attosecond pulses are short enough to capture the electronic dynamics in atoms and molecules. The work presented in this thesis deals with the generation and optimization of attosecond extreme-ultraviolet (XUV) pulses. READ MORE

6. 4. An Intense Attosecond Light Source - from Generation to Application

   Author : Linnea Rading; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-order Harmonic Generation; Intense XUV pulses; Velocity map imaging spectrometer; Fysicumarkivet A:2017:Rading;

   Abstract : Short and intense XUV pulses are important tools to study ultrafast dynamics and non-linear processes in matter. These pulses can be generated by free electron lasers (FELs) or by high-order harmonic generation (HHG), which are two complementary techniques. READ MORE

7. 5. An Intense Attosecond Light Source - Towards Extreme Ultraviolet Pump-Probe Experiments

   Author : Filippo Campi; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attosecond; Femtosecond; Ultrashort; Ultrafast; High-order Harmonic Generation; pump probe; XUV; Fysicumarkivet A:2017:Campi;

   Abstract : This thesis presents important steps towards performing high-intensity attosecond pump-probe experiments at the Lund high-intensity extreme ultraviolet (XUV) beamline, which followed two complementary paths: maximization of the XUV intensity available in the interaction region with a gas target, and providing attosecond temporal resolution.To maximize the energy of the XUV pulses generated via high-order harmonicgeneration (HHG), the macroscopic response of atoms to the driving infrared field was optimized.
