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.

"...provides the full, exciting story of optical modulators. ... a comprehensive review, from the fundamental science to the material and processing technology to the optimized device design to the multitude of applications for which broadband optical modulators bring great value. ... Especially valuable in my view is that the authors are internationally known researchers, developers, and systems people who are experts in their field, writing now, with the perspective that time offers, about their groundbreaking work. " —Dr. Rodney C. Alferness, Senior Vice President of Optical Networking Research at Lucent Technologies’ Bell Labs Considered the most comprehensive book yet published on this critical subject, Broadband Optical Modulators: Science, Technology, and Applications offers an incredibly wide-ranging yet in-depth overview of the state of the art in the design and use of optical modulators. A compilation of expert insights, this book covers fundamental and practical aspects, from materials to systems, addressing historical and more recent developments. Coverage includes: Optical and electro-optic properties of traditional single crystalline lithium niobate, silicon, and III-V compound semiconductors, as well as emerging electro-optic polymers and organic nonlinear optic crystals Discussion of factors important to modulator design, fabrication, and performance Fundamental topics, such as electro-optic effect in nonlinear optic crystals and semiconductors Leaders in the field created this invaluable reference for scientific researchers involved in high-speed device research and development, especially in the areas of optical transmitters and optical modulators for fiber-optics communication systems. Helping readers master optical modulation techniques, this book will be invaluable to engineers (system/subsystem designers, product developers, and technical and project managers) and other professionals in the telecommunications and defense industries. It offers the audience—which includes graduate students—an in-depth understanding of the new modulator architectures and technologies now available, as well as the strengths, weaknesses, advantages, and trade-offs associated with each.

The archaeological geology of the Quaternary or the geological epoch during which humankind evolved is a scientific endeavor with much to offer in the fields of archaeology and palaeoanthropology. Earth science techniques offer diverse ways of characterizing the elements of past landscapes and archaeological facies. This book is a survey of techniques used in archaeological geology for the study of soils, sediments, rocks and minerals. The techniques presented represent those most commonly used today. They are discussed in detail and examples are provided, in many cases, to demonstrate their usefulness to archaeologists.
