1. Quantum Optical Description of High-order Harmonic Generation
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : 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.

2. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

3. III-V semiconductor waveguides for application in nonlinear optics.
University essay from KTH/Tillämpad fysikAbstract : This thesis presents studies on III-V semiconductor waveguides with particular emphasis on second-order optical nonlinearity. The nonlinear processes that were investigated in this thesis are the Second Harmonic Generation (SHG) and the Spontaneous Parametric Down-Conversion (SPDC). READ MORE

4. Semi-Classical Calculations of Multiple Trajectories in High-Harmonic Generation
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : 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.

5. Generation and Characterization of Intense Attosecond Pulses
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. READ MORE
