Sammanfattning : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. LÄS MER
Sammanfattning : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. LÄS MER
Sammanfattning : Nonlinear microscopy techniques provide abilities for noninvasive and selective imaging of structural and chemical properties of biological systems. These techniques include coherent anti-Stokes Raman scattering (CARS) microscopy with the ability to selectively image molecular vibrations, second harmonic generation (SHG) microscopy which selectively images fiber structures, and third harmonic generation (THG) microscopy which is sensitive to interfaces between materials with different optical properties.

Sammanfattning : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. LÄS MER
