Abstract

Generating intense radiation in the wavelength band of the extreme ultraviolet (XUV, 100 to 10 nm) remains a very challenging goal in today’s scientific research. In this thesis, we describe a unique XUV source based on high harmonic generation. We have thoroughly investigated a number of intrinsic properties of high harmonic generation in a waveguided geometry. We conclude that using waveguides allows for spatial and spectral control of high-harmonic radiation. Our studies have also shown that waveguided high harmonic generation is particularly suited for producing radiation at XUV wavelengths with excellent beam coherence and unique spectral features. Future work, focused on using higher drive laser energy and larger waveguide diameters offer the potential of achieving higher XUV output energy.
