  1. 1. Quantum Optical Description of High-order Harmonic Generation

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

    Author : Isabel Moreno; [2024]
    Keywords : Physics and Astronomy;

    Abstract : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

  3. 2. E-Band SPDT RF Switch for a Class F PA in III-V Nanowire MOSFET Technology

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Rungeng Xu; [2022]
    Keywords : E-band; III-V Nanowire MOSFET; RF Switch; Class-F PA; Technology and Engineering;

    Abstract : This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. READ MORE

  4. 3. Soft Energization and Blackout Recovery of Offshore Wind Farm Export System

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nicolas Mile; [2022]
    Keywords : STATCOM; ES-STATCOM; Blackout; Blackstart; Energization; Restoration; Offshore Wind; Power System; STATCOM; ES-STATCOM; Strömavbrott; Svartstart; Spänningssätta; Återställning; Havsbaserad Vindkraft; Energisystem;

    Abstract : Power generation of the future will be dominated by renewable energy sources. This is a positive trend as society aims to improve sustainability, energy security, and reduce CO2 emissions. This progress however bears challenges for the power systems of the future. READ MORE

  5. 4. Semi-Classical Calculations of Multiple Trajectories in High-Harmonic Generation

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

    Author : Tom Causer; [2021]
    Keywords : hhg; high harmonic generation; trajectories; xuv; semi-classical; multiple; third trajectory; further; matlab; hhg approximation; simulation; far-field; near-field; fourier transform; Physics and Astronomy;

    Abstract : The purpose of this thesis is to investigate the High-Harmonic Generation (HHG) process by simulating electron trajectories, and their resulting Extreme Ultra Violet (XUV) output. The HHG process is one in which a focused beam of infrared (IR) light can rival (in terms of intensity) the potentials of atoms, which makes tunnelling likely -- this sets off a chain of events resulting in an XUV pulse.

  6. 5. Manipulation and application of laser light using spatial light modulation

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

    Author : Albin Hedse; [2020]
    Keywords : spatial light modulation; wavefront correction; high harmonic generation; harmonic divergence; Physics and Astronomy;

    Abstract : Attosecond pulses obtained via high harmonic generation often suffer from chromatic aberration. This is inherent from the generation process as a consequence of the spatial profile of the driving laser pulses. READ MORE
