1. Optically pumped semiconductor disk lasers for high-power wide wavelength tuning
Sammanfattning : In this work I present and verify a strategy that makes it possible to change the wavelength, or color, of an external cavity semiconductor laser over a very large range. This is achieved by a careful design and thorough optimization of the active component — the gain element of the laser. LÄS MER
2. Design and Performance of Optically Pumped Semiconductor Disk Lasers with Wide Tuning Ranges
Sammanfattning : In this work I present a strategy for providing the possibility to select the wavelength, or color, of a semiconductor laser over a very large range, by cleverly designing the vital part of the laser: the gain element of a so called optically pumped semiconductor disk laser. Optically pumped semiconductor disk lasers (OP-SDLs) are a relatively new class of lasers showing great promise for future applications. LÄS MER
3. High Power, Long Wavelength Semiconductor Disk Lasers for Continuous and Mode-Locked Operation
Sammanfattning : The semiconductor disk laser has recentlyemerged as an attractive alternative to bulky and power consuming gas and solid state lasers. It offers compact, powerful and efficient devices with W level output power and beam properties earlier not achieved with semiconductor lasers. LÄS MER
4. Grating Based Lasers for Photonic Integration and Surface Emission
Sammanfattning : This thesis deals with the fabrication and characterization of grating-based integration-compatible semiconductor lasers. Waveguide gratings provide feedback for the laser resonators, and are used to diffract the laser output out of the waveguide for surface-emission. LÄS MER
5. High-Order Harmonics- Characterisation, Optimisation and Applications
Sammanfattning : Recent advances in laser technology, with the development of extremely short-pulse, high-intensity lasers, have opened doors to new areas in atomic physics. By focusing light from an intense, short-pulse laser into a gas jet, the emission of high-order harmonics of the laser frequency has been studied. LÄS MER
