The presented thesis introduces our work of extending high-resolution x-ray 3D imaging towards extended samples. With the advent of x-ray sources with higher brightness and better coherence, as well as the rise of the needs to examine the fine structures of large objects in the field of materials science, biology,...
Optical interferometry is a powerful technique which has been widely utilized for well over a century in making the world’s most precise measurements. By measuring how the interference between two waves is affected by a physical process, one can deduce the magnitude of this process. Because the wavelength of a...
Experimental and numerical studies of lasing in multiple light scattering media with gain are presented in this thesis. Depending on the dielectric constant spatial distribution is random or periodic, two different kinds of lasers are discussed: the random laser and the photonic crystal laser. This thesis, therefore, is divided into...
