Foreword by Nobel laureate Professor Theodor W. Hänsch of Ludwig-Maximilians-Universität MünchenBased on the authors’ experimental work over the last 25 years, Laser-Based Measurements for Time and Frequency Domain Applications: A Handbook presents basic concepts, state-of-the-art applications, and future trends in optical, atomic, and molecular physics. It provides all the background information on the main kinds of laser sources and techniques, offers a detailed account of the most recent results obtained for time- and frequency-domain applications of lasers, and develops the theoretical framework necessary for understanding the experimental applications. After a historical introduction, the book describes the basic concepts and mathematical tools required for studying the physics of oscillators. It then discusses microwave and optical resonators, crucial aspects of operation and fundamental properties of lasers, and precision spectroscopy and absolute frequency metrology. It also focuses on microwave and optical frequency standards and explores current and potential research directions.Accessible to scientists, postdoc researchers, and advanced undergraduate students, this self-contained book gives a wide-ranging, balanced overview of the areas—including frequency standards and clocks, ultra-high-precision spectroscopy, quantum information, and environmental metrology—revolutionized by the recent advent of optical frequency comb synthesizers (OFCSs) based on femtosecond mode-locked lasers. The book is also a useful guide to cutting-edge research for manufacturers of advanced laser systems and optical devices.

Starting from basic concepts, this book provides a comprehensive review of cutting-edge experimental research in the field of infrared precision molecular spectroscopy and absolute frequency metrology. Ranging from the near-infrared to the THz region, state-of-the-art narrow- and broad-band coherent radiation sources with corresponding frequency stabilization methods are described. The most sophisticated high-sensitivity and high-resolution spectroscopic techniques are then discussed, along with an overview of the most recent record-breaking measurements. Relying on improved samples enabled by emerging technologies for producing cold stable molecules, in conjunction with superior frequency standards delivered by modern optical fiber networks, perspectives for further refining spectroscopic performance in terms of ultimate attainable precision are also considered. Finally, exciting new developments are discussed that encompass increasingly refined tests of fundamental physics, quantum metrology and sensing, quantum simulation and computation with ultracold molecules. The book is aimed at researchers passionate about infrared laser sources and molecular spectroscopy, both as a useful guide for the design of advanced experiments and as a text for advanced university courses.

The idea to write a new book in the ?eld of ferroelectric crystals arose from some considerationsreportedinthefollowing. Inthelast5years,severalgroupsallaround the world in the ?eld of engineering and characterization of ferroelectric crystals have published more than 300 papers. The motivation for such an intense research activity is referable to the fact that the ferroelectric crystals are a key element for the most attractive and useful photonic and optoelectronic devices. In fact, during the 60ies, the scientists realized that the ferroelectric crystals could have been - ?ciently used to generate new, unavailable frequencies, taking advantage of the freshly proposed birefringent phase-matching method. The synchronized rush for the development of novel coherent sources and for the discovery of the best-suited nonlinear crystals for mixing and generation had started. Consequently, the range of applications of ferroelectric crystals has enormously widened in the last years, es- cially based on the use of periodically poled structures (i. e. , PPLN, PPLT, PPKTP, or PPKTA) to quasi-phase-match optical interactions. A new generation of sources is ?nding increasing applications in various ?elds, including high sensitivity trace gas monitoring and any kind of advanced spectroscopic set-ups, thus replacing “old style” gas lasers like Argon-ion or dye lasers. New possibilities are also being - plored to engineer ferroelectric crystals with two- or three-dimensional geometries. Results from this ?eld will allow developing photonic devices combining photonic band-gap properties and nonlinear conversion processes, i. e. , nonlinear photonic crystals.
