… of the relevant physics at the level of current high-precision spectroscopy. In this thesis, several calculations in this area are described in detail. Investigations on large-order perturbation-theory effects (and predictive limits of perturbation theory) supplement these investigations. In the …

High-power deep-UV laser for improved and novel experiments on hydrogen
… performance, and cavity enhancement of a novel, high-power coherent 243.1 nm laser system, and through simulations, its ability to trap hydrogen in a magic wavelength optical trap. This wavelength of light is necessary to address the 1S–2S two-photon transition in hydrogen, and the primary …

Dead time and count loss determination for radiation detection systems in high count rate applications
… can be important in many applications including high-precision spectroscopy, positron emission tomography (PET), and the scanning of spent nuclear fuel. Understanding of the behavior of radiation detection systems is important; thus this work included a comprehensive review of dead time and pulse …

High-accuracy and high-precision infrared spectroscopy of fundamental molecular ions using noise immune cavity enhanced optical heterodyne velocity modulation spectroscopy
… quantities such as energy levels and spectra. High accuracy calculations that achieve ``spectroscopic accuracy"" (i.e. energy levels and spectra that are accurate to < 1 cm-1) are only possible for a select few molecular systems, and as such these systems are of great fundamental interest as …

Sensitive and high-precision rovibrational spectroscopy of molecular ions relevant to astronomical and quantum chemistry
High-precision spectroscopy of molecular ions has enabled new discoveries in astronomy and provided valuable benchmarks for ab initio calculations of molecular structure. Astronomers and theorists require accurate and precise laboratory measurements of rotational and rovibrational transition …

Vacuum-mediated incoherent processes in coherently prepared media
… atoms as an interesting candidate for high-precision spectroscopy. <br>For this, we combine ideas from quantum optics and quantum <br>electrodynamics (QED). This can be seen as a first step to treat dynamical <br>processes within the framework of QED. <br>As an application, the outcome …
