1. Diode-pumped Nd : YAG lasers for generation of blue light by frequency doubling
Sammanfattning : Quasi-three-level lasers in neodymium-doped crystals such asNd:YAG, Nd:YLF and Nd:YVO4have received a great deal of interest becausethey allow generation of blue light by frequency doubling. Forsolid-state blue laser sources, there exist numerousapplications as in high-density optical data storage, colourdisplays, submarine communication and biologicalapplications. LÄS MER
2. On diode-pumped solid-state lasers
Sammanfattning : The research that is presented in this thesis can be divided into two major parts. The first part concerns longitudinally pumped, bulk Er-Yb lasers. In these lasers, the main limitation is the thermal shortcomings of the phosphate glass host material. LÄS MER
3. Development and Characterization of Reliable Graphene-based Materials for Lightweight and Efficient Thermal Management in Electronics
Sammanfattning : The semiconductor industry continuously aims to increase the transistor density in integrated circuits to improve performance of electronics. As performance and transistor density increases, so does the power density of integrated circuits. LÄS MER
4. Modelling and design of high-power HBV multipliers
Sammanfattning : This thesis deals with symmetric varactor frequency multipliers for millimetre and sub-millimetre wave applications. Much of the material presented is general and applicable to any type of (symmetric) varactor, but the focus is on the heterostructure barrier varactor (HBV). The basic function and principles of HBVs are explained. LÄS MER
5. Experimental Studies of Charge Transport in Single Crystal Diamond Devices
Sammanfattning : Diamond is a promising material for high-power, high-frequency and high- temperature electronics applications, where its outstanding physical properties can be fully exploited. It exhibits an extremely high bandgap, very high carrier mobilities, high breakdown field strength, and the highest thermal conductivity of any wide bandgap material. LÄS MER
