The dissertation is devoted to development and experimental implementation of 1-kHz, coherent extreme ultraviolet (XUV) radiation source based on high-order harmonic generation of the femtosecond near-infrared laser pulses generated by the titanium sapphire laser system (35 fs, 1.2 mJ, 810 nm) at the Institute of Physics AS CR / PALS Centre. The source comprises a lowdensity gas cell filled with conversion medium, typically argon. Comprehensive optimization of the XUV harmonic source was performed with respect to major source parameters such as gas pressure in the gas cell, gas cell length, position of the focus of the driving laser field with respect to the gas cell position, size of the driving near-infrared laser beam, chirp of the femtosecond pulse and focal length of the lens deployed in the experimental setup. Harmonic spectra were recorded using a new XUV transmission grating spectrometer developed within this thesis.
