1. Performance Estimation of a 1D pulsed LiDAR : A Study of SiPM-Based LiDAR in Ambient Light
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : LiDAR is a remote sensing technology that uses a laser to map the surrounding environment. With its many applications, for example in autonomous vehicles, LiDAR is a growing field within technology and research. The silicon photomultiplier (SiPM) is a solid state device commonly used in the receiving system of a LiDAR. LÄS MER
2. Development of MOKE spectrometer
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/MaterialfysikSammanfattning : The magneto-optical Kerr effect (MOKE) describes the change in polarization of light reflected from a magnetic surface. This change is proportional to the magnetization and depends on the wavelength of light. Because of these properties, MOKE has found use as a tool to probe magnetism in matter. LÄS MER
3. Frekvensdubbling i kvasifasmatchad Rb-dopad KTiOPO4 med temperaturgradient för 1030nm laser
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Denna avhandling går ut på att undersöka verkningsgradens temperaturberoende för SHG (second harmonic generation) från 1030nm till 515nm, i en kvasifasmatchad KTP-kristall, för både pulsad och CW (continuous wave)-laser. Detta undersöktes då det har tidigare noteras att verkningsgraden hos en KTP-kristall avtar när effekten på lasern ökar. LÄS MER
4. The Development of a Model for Determining the Spatial Resolution of Pulsed-Neutron Sources
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning across a one dimensional object of known dimensions.

5. Study on the Electronic Band Structure of the Spinel Superconductor LiTi2O4
Master-uppsats, KTH/Tillämpad fysikSammanfattning : This master’s thesis focuses on investigating the electronic properties of the superconducting spinel compound LiTi2O4 by means of computational and experimental effort. The title compound has been extensively studied in the past years, being the only known superconducting spinel oxide with relatively high Tc = 11.5 K. LÄS MER
