11. Short Attosecond Pulse Trains at High Repetition Rates for Novel Pump-Probe and Coincidence Studies
Abstract : This work aims at studying photoionization dynamics from atoms and surfaces at attose time scales. The work was based on development and applications of a high repetition rate High-order Harmonic Generation (HHG) light source that utilizes Optical Parametric Amplification (OPA) laser technology.

12. Higher harmonic cavities at 3rd generation synchrotron light sources
Abstract : Synchrotron radiation is a tool widely used in science. It is produced by electron accelerators called storage rings. With the high performance of the 3rd generation synchrotron light sources, the scientific results are excellent. It is important to identify and overcome the limitations of a storage ring in order to enhance its performance. READ MORE

13. Control of Coherent Extreme Ultraviolet Light and Light Sources
Abstract : Coherent extreme ultraviolet (XUV) light sources are necessary for the investigation of physical processes in the natural length and time scales of atoms. These experiments require a high degree of control of the coherent XUV light. READ MORE

14. Spatial and temporal metrology of intense attosecond pulses
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

15. Towards ultrafast imaging with extreme ultraviolet light sources
Abstract : This thesis reports experimental studies performed with two advanced coherent XUV sources with ultrashort pulse duration, high-order harmonic generation and seeded-free electron laser. High-order harmonic generation (HHG) is the generation of overtones of a fundamental laser pulse in a medium, e.g. noble gases. READ MORE
