This thesis focuses on the application of optical magnetometry to magnetic resonance experiments. After an introduction of the basics of magnetic resonance and optical magnetometry it discusses imaging and spectroscopic applications. Two magnetomers are described; one was constructed in the Pines lab and uses frequency modulated non-linear magneto-optics, while the other was constructed in the Budker lab and is based on a spin-exchange relaxation free technique. An Earth's field MRI device was used in the first two experiments discussed. This device imaged the flow of water through a porous steel sample and through a T-shaped mixer. The third experiment discussed is a one-dimensional imaging technique. The final experiment discussed uses the Budker lab magnetometer to determine J-coupling values at zero field.

This book presents the important analytical technique of magnetic microscopy. This method is applied to analyze layered structures with high resolution. This book presents a number of layer-resolving magnetic imaging techniques that have evolved recently. Many exciting new developments in magnetism rely on the ability to independently control the magnetization in two or more magnetic layers in micro- or nanostructures. This in turn requires techniques with the appropriate spatial resolution and magnetic sensitivity. The book begins with an introductory overview, explains then the principles of the various techniques and gives guidance to their use. Selected examples demonstrate the specific strengths of each method. Thus the book is a valuable resource for all scientists and practitioners investigating and applying magnetic layered structures.

Laser physics has always been driven by a genuinely scientific quest to extend existing limits, limits of physical knowledge and limits of physical methods. Enhancing precision, sensitivity, and resolution has been an essential topic of this evolution. Experiments and concepts of laser physics have also earned a central place in modern physics. More than 100 years after the invention of quantum physics, subtleties of light-matter interaction can be beautifully illustrated through the application of lasers, an invaluable highlight of our current presentation of modern microscopic physics. The scientific advancement of physics is impossible without the ingenuity of experimenters and of theoreticians. Among those, Theodor Hänsch has oc cupied a commanding position for many decades now, contributing numerous original and fundamental contributions to the field of laser physics. This vol urne was thus initiated on the occasion of his 60th birthday. It demonstrates the influence of his scientific activities at present and during the recent past. Current developments in fields such as atomic elocks, precision measurements of fundamental constants, nonlinear optical effects, Bose-Einstein condensa tion, and atomic quantum engineering underline the virtue of concepts and results derived in his laboratories.

Atomic ensembles have assumed a central role in modern high precision sensing applications including atomic clocks, magnetometers, gravimeters, and accelerometers. In the past decade significant advances have been made pushing these sensors to, and in some cases beyond the standard quantum limit of sensitivity. Much recent interest has been in the use of Quantum Non-Demolition (QND) measurements to perform state-preparation and metrology simultaneously. QND measurements are typically accomplished through interaction with an off-resonant optical probe. I present techniques to recreate QND measurements in the case that the Probe-Atom interaction is non-QND due to the presence of a tensor light-shift Hamiltonian. The tensor interaction naturally arises in detuned systems with spin one or higher and leads to a series of effects, including Hamiltonian evolution, technical noise enhancement, inhomogeneous and homogeneous dephasing that reduce measurement accuracy in these systems. I demonstrate several techniques for active cancellation of the tensor Hamiltonian and show compatibility with QND measurement and sub-shotnoise metrology performance.

Magnetoencephalography (MEG) is an invaluable functional brain imaging technique that provides direct, real-time monitoring of neuronal activity necessary for gaining insight into dynamic cortical networks. Our intentions with this book are to cover the richness and transdisciplinary nature of the MEG field, make it more accessible to newcomers and experienced researchers and to stimulate growth in the MEG area. The book presents a comprehensive overview of MEG basics and the latest developments in methodological, empirical and clinical research, directed toward master and doctoral students, as well as researchers. There are three levels of contributions: 1) tutorials on instrumentation, measurements, modeling, and experimental design; 2) topical reviews providing extensive coverage of relevant research topics; and 3) short contributions on open, challenging issues, future developments and novel applications. The topics range from neuromagnetic measurements, signal processing and source localization techniques to dynamic functional networks underlying perception and cognition in both health and disease. Topical reviews cover, among others: development on SQUID-based and novel sensors, multi-modal integration (low field MRI and MEG; EEG and fMRI), Bayesian approaches to multi-modal integration, direct neuronal imaging, novel noise reduction methods, source-space functional analysis, decoding of brain states, dynamic brain connectivity, sensory-motor integration, MEG studies on perception and cognition, thalamocortical oscillations, fetal and neonatal MEG, pediatric MEG studies, cognitive development, clinical applications of MEG in epilepsy, pre-surgical mapping, stroke, schizophrenia, stuttering, traumatic brain injury, post-traumatic stress disorder, depression, autism, aging and neurodegeneration, MEG applications in cognitive neuropharmacology and an overview of the major open-source analysis tools.
