Abstract: Compact brilliant attosecond electron and x-ray sources promise to bring wide-spread access to groundbreaking scientific, technological, and medical tools. In the pursuit of such visionary technology, this thesis describes in detail three key scientific and technological feasibility advances towards the development of novel electron and x-ray sources based entirely on optical lasers. The main areas covered are (i) high average- and peak-power optical laser development, (ii) efficiency scaling and limitations of terahertz radiation generation, and (iii) direct longitudinal laser acceleration of electrons in vacuum. In (i) we will point at Yb:YLF technology as a candidate for optical energy scaling at high repetition rates and sub-ps pulse durations, and will present a thorough front-end design and preliminary experimental results. In (ii) we will describe in detail theoretical and experimental aspects of the primary mechanisms that contribute to increasing and ultimately saturating the optical-toterahertzenergy conversion efficiency in lithium niobate through optical rectification, and show the highest efficiency demonstrated to date. In (iii) we will expound on the first-time demonstration of longitudinal acceleration of electrons using relativistic radially-polarized few-cycle pulses in an entirely free-space environment. Throughout the thesis and specially in the introduction, we will discuss how each independent topic relates to one anotherand ultimately integrates into the concept of compact relativistic electron and bright x-ray sources.
