2. Novel materials for Yb and Er-Yb doped microchip lasers
Abstract : The objective of this thesis has been to investigate novel host material configurations for high-power end-pumped Er-Yb co-doped, or Yb doped microchip lasers and try to increase their performance. In Er-Yb co-doped systems, the main limitation is the thermal shortcomings of the phosphate glass host material. READ MORE

3. On diode-pumped solid-state lasers
Abstract : 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. READ MORE

4. Knowledge for Improving Healthcare Service Quality : Combining Three Perspectives
Abstract : The Swedish public sector in general, and healthcare specifically, is struggling with large deficits: 19 of 21 regions have large negative results in 2019. The demands made by the citizens and their elected politicians that healthcare should offer effective, accessible, good and equal care are difficult to meet. READ MORE

5. Numerical computations of the unsteady flow in a radial turbine
Abstract : Non-pulsatile and pulsatile flow in bent pipes and radial turbine has been assessed with numerical simulations. The flow field in a single bent pipe has been computed with different turbulence modelling approaches. READ MORE
