Book excerpt: An offset laser lock is an optoelectronic system capable of stabilizing a laser's optical frequency to a variable offset from another stable laser's frequency. The lock system described in this report relies on a digital frequency comparison of the beat note of two lasers to determine and fix the frequency difference, or offset, between them. This thesis describes the construction of a configurable proportional-integral (PI) control circuit to regulate a laser's frequency based on the error signal generated by a digital comparison of the beat note frequency, as well as the integration of formerly unconnected circuit elements within the laser lock. Testing confirms the proper operation of both the PI circuit and the laser lock system.

Available in PDF, EPUB and Kindle. Book excerpt: Because of the favorable characteristics of solid-state lasers, they have become the preferred candidates for a wide range of applications in science and technology, including spectroscopy, atmospheric monitoring, micromachining, and precision metrology. Presenting the most recent developments in the field, Solid-State Lasers and Applications focuses on the design and applications of solid-state laser systems. With contributions from leading international experts, the book explores the latest research results and applications of solid-state lasers as well as various laser systems. The beginning chapters discuss current developments and applications of new solid-state gain media in different wavelength regions, including cerium-doped lasers in the ultraviolet range, ytterbium lasers near 1μm, rare-earth ion-doped lasers in the eye-safe region, and tunable Cr2+:ZnSe lasers in the mid-infrared range. The remaining chapters study specific modes of operation of solid-state laser systems, such as pulsed microchip lasers, high-power neodymium lasers, ultrafast solid-state lasers, amplification of femtosecond pulses with optical parametric amplifiers, and noise characteristics of solid-state lasers. Solid-State Lasers and Applications covers the most important aspects of the field to provide current, comprehensive coverage of solid-state lasers.

Available in PDF, EPUB and Kindle. Book excerpt: The Tunable Lasers and Applications Conference was held in Loen, Norway, on June 6-11, 1976. This conference dealt with the technology of tunable lasers from the vacuum ultraviolet to the far infrared and their application in the areas of photochemistry, chemical kinetics, isotope separation, at mospheric photochemistry and environmental studies, photobiology, and spec troscopy. The need for such a conference grew out of the rapidly expanding use of tunable lasers in a broad range of disciplines. The conference was attended by 130 scientists representing Japan, Italy, West Germany, Canada, Israel, France, England, Norway, Sweden, Brazil, Den mark, Finland, the Netherlands, the Soviet Union, and the United States. The location of the conference in Loen, Nordfjord, was chosen because of the magnificent beauty of its aqua-blue fjords surrounded by glacier-capped mountains and lush green hillsides. The Alexandra Hotel was a perfect host for such a conference with first class services, superb smorgesbord, and ex cellent audio-visual facilities. The atmosphere was free of distractions and provided for a relaxed interchange of ideas. An afternoon hike was arranged to the Briksdal glacier while the highlight of the outdoor activities was a bus-ship excursion to the magestically splendid Geiranger fjord. A sumptuous banquet was followed by an interesting'and entertaining illustrated talk on high-speed and underwater photography by Professor Harold Edgerton from MIT. Financial support from our sponsors is gratefully acknowledged in help ing to make this conference a complete success.

Book excerpt: A fascinating account, written in real time, of the unfolding of a scientific discovery: the first detection of gravitational waves. Scientists have been trying to confirm the existence of gravitational waves for fifty years. Then, in September 2015, came a “very interesting event” (as the cautious subject line in a physicist's email read) that proved to be the first detection of gravitational waves. In Gravity's Kiss, Harry Collins—who has been watching the science of gravitational wave detection for forty-three of those fifty years and has written three previous books about it—offers a final, fascinating account, written in real time, of the unfolding of one of the most remarkable scientific discoveries ever made. Predicted by Einstein in his theory of general relativity, gravitational waves carry energy from the collision or explosion of stars. Dying binary stars, for example, rotate faster and faster around each other until they merge, emitting a burst of gravitational waves. It is only with the development of extraordinarily sensitive, highly sophisticated detectors that physicists can now confirm Einstein's prediction. This is the story that Collins tells. Collins, a sociologist of science who has been embedded in the gravitational wave community since 1972, traces the detection, the analysis, the confirmation, and the public presentation and the reception of the discovery—from the first email to the final published paper and the response of professionals and the public. Collins shows that science today is collaborative, far-flung (with the physical location of the participants hardly mattering), and sometimes secretive, but still one of the few institutions that has integrity built into it.

This book was released on 2006-06-15 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years, there has been a convergence between the fields of ultrafast science, nonlinear optics, optical frequency metrology, and precision laser spectroscopy. These fields have been developing largely independently since the birth of the laser, reaching remarkable levels of performance. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.
