1. 1. Improving the experimental setup for ultrasound-optical tomography imaging

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ibtisam Dahir Ahmed; [2023]
   Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

   Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE

3. 2. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

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

   Author : Vidar Flodgren; [2019]
   Keywords : GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

   Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

4. 3. Experimental Investigation of Fuel Mixing Concepts for 3rd Generation DLE Burners : Evaluation Through Water Rig and Atmospheric Combustion Rig Measurements

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Jonathan Lönning; [2016]
   Keywords : ;

   Abstract : New Siemens burner concepts thought to produce a more homogeneous air/fuel mix-ture and a better distribution of the fuel over the burner cross section have been evaluated. A homogeneous air/fuel mixture is known to produce the lowest levels of emitted oxides of nitrogen (NOx) which is a main objective for Siemens Industrial Turbomachinery AB (SIT). READ MORE

5. 4. Design of Multilayer Dielectric Mirrors Optimized for Femtosecond Laser Pulses

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

   Author : Fredrik Bertilsson; [2015]
   Keywords : Physics and Astronomy;

   Abstract : A general method for modelling reflection in a multilayer structure is developed. This is used to simulate how a Gaussian Ti:sapphire femtosecond pulse reflects off of a periodic SiO2/TiO2 dielectric stack at normal incidence. The method is based on a transfer matrix approach combined with the fast Fourier transform in MATLAB. READ MORE

6. 5. Interferometer Design for Attosecond Experiments

   University essay from Lunds universitet/Fysiska institutionen

   Author : Simon Ek; [2015]
   Keywords : FRED; attophysics; atomic physics; stability; simulations; MATLAB; interferometer design; interferometers; error propagation; Physics and Astronomy;

   Abstract : Resolving fast events, such as electron dynamics, requires short light pulses. To this date the shortest available light pulses are created using High-order Harmonic Generation (HHG) and have a duration of a few hundred attoseconds (1 as = $10^{-18}$ s). READ MORE
