description: The thesis is devoted to the analytical and numerical studies of high-order harmonic generation and super-intense single attosecond pulse emission via ultra-relativistic laser-plasma interaction. In the ultra-relativistic regime, the laser radiation pressure induces plasma ion motion through the so called hole-boring effect, resulting in frequency widening of the harmonic spectra. This widening, analyzed analytically and validated by particle-in-cell simulations, produces a quasi-continuous frequency spectrum, a prerequisite for generating an intense single attosecond pulse. Based on the results and physical considerations, parameter maps highlighting the optimum regions for generating a single intense attosecond pulse and coherent XUV radiation are presented. Moreover, a robust plasma gating is developed to generate a super-intense phase-stabilized single attosecond pulse. The hole-boring effect limits the most efficient high-frequency emission in one  laser cycle making it possible to isolate a single attosecond pulse. The generated pulse is characterized by a stabilized spectral phase ψ(ω) ≈ ±π/2 and an ultra-broad exponential spectrum up to keV region bounded by ROM scaling and CSE scaling. The unprecedented intensity highlights the potential of the isolated attosecond pulse for performing  attosecond-pump attosecond-probe experiments.
