1. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering
University essay from Uppsala universitet/FREIAAbstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

2. Simulations and modeling of light propagation in biological tissue
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska HögskolaAbstract : The GASMAS technique has previously proven useful for examining and measuring the oxygen concentration in the lungs of preterm infants. GASMAS can distinguish absorption by one gas from the bulk absorption of the surrounding media, and can provide an instant, non-invasive and non-destructive way of examining lungs, and diagnosing dangerous conditions such as pneumothorax.

3. Development of MOKE spectrometer
University essay from Uppsala universitet/MaterialfysikAbstract : 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. READ MORE

4. Modeling a Tunable Narrow Linewidth Laser
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this report a model of a tunable narrow linewidth laser used for telecommunications is presented. The model uses both theoretical analysis and experimental data to create the mathematical models governing its behaviour and is aimed to be useful in a development environment with requirements on accuracy, efficient implementation and adaptability to future design.

5. Development and characterization of tissue-mimicking phantom materials for photoacoustic imaging
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. READ MORE
