6. Fish Lenses : Anatomy and Optics
Sammanfattning : I have investigated some of the biological regulatory mechanisms governing the development of crystalline lenses. I used fish as model animals because they possess optically interesting lenses, while the geometrical simplicity of fish lenses allows for studies that are difficult or impossible with the lenses of other animals.

7. Cataract from ultraviolet radiation in the mouse
Sammanfattning : Cataract is defined as an opacification of the crystalline lens that results in visual impairment, Cataract is the number one cause of blindness in the world and there are currently no strategies to prevent it. Extraction of cataractogenous lenses is the most commonly performed surgical intervention in industrialized countries. LÄS MER
8. Long-term results of phakic refractive lenses (PRL) for correction of myopia and hyperopia
Sammanfattning : The phakic refractive lens (PRL) is a silicone lens implanted into the posterior chamber to correct myopia and hyperopia. At the beginning of 2002, when the PRL was introduced at St. LÄS MER
9. Novel materials for Yb and Er-Yb doped microchip lasers
Sammanfattning : 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. LÄS MER
10. 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
