Passive Optical Resonators for Next-Generation Attosecond Metrology

This book explores the development of high-pulse-repetition-frequency instruments for multi-dimensional attosecond-resolution photoelectron spectroscopy (attosecond PES). It investigates power scaling of femtosecond enhancement cavities for efficient intracavity high-harmonics generation (HHG), derives and verifies advanced resonator designs with large illuminated spots, and quantitatively investigates the dynamics of a high-finesse, passive resonator in the presence of HHG. It also demonstrates coupling out the XUV beam from the enhancement cavity by purely geometric means, offering robustness, low distortion, and photon-energy scalability. Additionally, it provides proof-of-principle attosecond angle-resolved PES experiments and discusses the potential future development of cavity-enhanced HHG and isolated XUV attosecond pulse generation via intracavity wavefront rotation.

This comprehensive book delves into the development of a novel generation of high pulse-repetition frequency instruments for multi-dimensional attosecond-resolution photoelectron spectroscopy (attosecond PES). It explores the power scaling of femtosecond enhancement cavities to efficiently generate high-harmonics (HHG) within the cavity. Furthermore, it derives and verifies advanced resonator designs featuring large illuminated spots on all mirrors, mitigating intensity- and thermally-induced enhancement limitations.

The book conducts a quantitative investigation into the dynamics of a high-finesse, passive resonator in the presence of HHG, employing both theoretical and experimental approaches. These investigations play a crucial role in achieving the holistic optimization of the XUV source reported in the book, which, for the first time, achieved intracavity HHG conversion efficiencies comparable to those achieved in single-pass setups with a similar gas target.

To couple out the XUV beam from the enhancement cavity, the author explores the use of purely geometric means, employing both the fundamental and higher-order transverse Gaussian modes. This approach offers several advantages, including robustness, low distortion to the participating pulses, and scalability in terms of photon energy. Additionally, the author presents a range of proof-of-principle attosecond angle-resolved PES experiments.

The book provides an insightful outlook on the potential future development of cavity-enhanced HHG and offers an extensive discussion on generating isolated XUV attosecond pulses via intracavity wavefront rotation. It serves as a valuable resource for researchers and practitioners in the field of attosecond science and technology.
