  1. 16. Optimization of Intense Attosecond XUV Pulses

    University essay from Umeå universitet/Institutionen för fysik

    Author : Xiuyu Wu; [2019]
    Keywords : ;

    Abstract : To observe electron dynamics in molecules and atoms which takes place on the attosecond timescale, single isolated attosecond pulses are required utilized in performing pump–probe experiments. The Light Wave Synthesizer 20 generates intense sub-5 fs pulses with a peak power of 16 TW and a broad spectrum. READ MORE

  3. 17. Design and Commissioning of an Ionization Intensity Monitor

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Hanna Berg; [2019]
    Keywords : Physics and Astronomy;

    Abstract : The dynamics of molecules and electrons takes place on timescales of femtoseconds and attoseconds, respectively. This requires ultrashort and intense extreme ultraviolet (XUV) pulses to be able to study them. READ MORE

  4. 18. Study of Dicke’s Model for Superradiance at Short Wavelengths from Core-excited Atoms

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Xiaolin Bian; [2019]
    Keywords : Physics and Astronomy;

    Abstract : The main objective of this study is to contribute toward a comprehensive understanding of the superradiance problem in a short wavelength regime ($100$ to $100$ eV). In this regime, superradiance is influenced by Auger effect which would compete with normal superradiance process, and we want to study if it is possible to generate ultra-short pulses on the femtosecond or attosecond timescale using Dicke superradiance.

  5. 19. All solid state single-shot Dispersion scan (D-Scan) for ultrashort laser pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Shekhar Jadhav; [2019]
    Keywords : Dispersion scan; d-scan; Single shot d-scan; Si-scan; Physics and Astronomy;

    Abstract : Ultrashort laser pulses play an important role in many applications in science and technology, from attosecond science to time resolved spectroscopy and material processing. For applications of ultrashort laser pulses, it requires a complete characterization of the electric field of the pulse, which includes both phase and amplitude of the electric field. READ MORE

  6. 20. Photoionization study using few attosecond pulses and coincidence imaging techniques

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Lisa Rämisch; [2019]
    Keywords : Laser spectroscopy; Attosecond Science; Electron Spectroscopy; Physics and Astronomy;

    Abstract : Photoionization is one of the most fundamental photoreactions that leads to the ejection of an electron and the formation of an ion. With the help of modern 3D momentum imaging spectrometers, the interplay between the time and frequency domain upon ionization is studied. READ MORE
