Evaluation of spatial-spectral filtering in non-paraxial volume holographic imaging systems
… this thesis, the properties of transmission-mode volume phase holograms as spatial-spectral filters in optical systems for microscopic medical imaging are evaluated. In experiment, the relationship between the angle of incidence and diffraction efficiency are invesitgated for wavelength-detuned …

Holographic Investigation of Azobenzene-Containing Low-Molecular-Weight Compounds
In the present thesis, holographic volume and surface relief gratings in azobenzene-containing low-molecular-weight compounds are investigated to obtain a broader understanding of this new class of material. Azobenzene chromophores undergo light-induced trans-cis-trans isomerization cycles leading …

Theoretical Study of Laser Beam Quality and Pulse Shaping by Volume Bragg Gratings
… compressing of short light pulses by the chirped volume Bragg gratings (CBG) is reviewed based on spectral decomposition of short pulses and on the wavelength-dependent coupled wave equations. The analytic theory of diffraction efficiency of a CBG with constant chirp and approximate theory of time …
