Book Description
This report is a synoptic investigation of the uses of frequency-stabilized lasers for scientific applications in space. It begins by summarizing properties of lasers, characterizing their frequency stability, and describing limitations and techniques to achieve certain levels of frequency stability. Limits to precision set by laser frequency stability for various kinds of measurements are investigated and compared with other sources of error. These other sources include photon-counting statistics, scattered laser light , fluctuations in laser power and intesity distribution across the beam, propagation effects, mechanical and thermal noise, and radiation pressure. -- From abstract.

Book Description
This book systematically introduces the single frequency semiconductor laser, which is widely used in many vital advanced technologies, such as the laser cooling of atoms and atomic clock, high-precision measurements and spectroscopy, coherent optical communications, and advanced optical sensors. It presents both the fundamentals and characteristics of semiconductor lasers, including basic F-P structure and monolithic integrated structures; interprets laser noises and their measurements; and explains mechanisms and technologies relating to the main aspects of single frequency lasers, including external cavity lasers, frequency stabilization technologies, frequency sweeping, optical phase locked loops, and so on. It paints a clear, physical picture of related technologies and reviews new developments in the field as well. It will be a useful reference to graduate students, researchers, and engineers in the field.

Book Description
The goal of the NASA Sunlite program is to fly two diode-laser-pumped solid-state lasers on the space shuttle and while doing so to perform a measurement of their frequency stability and temporal coherence. These measurements will be made by combining the outputs of the two lasers on an optical radiation detector and spectrally analyzing the beat note. Diode-laser-pumped solid-state lasers have several characteristics that will make them useful in space borne experiments. First, this laser has high electrical efficiency. Second, it is of a technology that enables scaling to higher powers in the future. Third, the laser can be made extremely reliable, which is crucial for many space based applications. Fourth, they are frequency and amplitude stable and have high temporal coherence. Diode-laser-pumped solid-state lasers are inherently efficient. Recent results have shown 59 percent slope efficiency for a diode-laser-pumped solid-state laser. As for reliability, the laser proposed should be capable of continuous operation. This is possible because the diode lasers can be remote from the solid state gain medium by coupling through optical fibers. Diode lasers are constructed with optical detectors for monitoring their output power built into their mounting case. A computer can actively monitor the output of each diode laser. If it sees any variation in the output power that might indicate a problem, the computer can turn off that diode laser and turn on a backup diode laser. As for stability requirements, it is now generally believed that any laser can be stabilized if the laser has a frequency actuator capable of tuning the laser frequency as far as it is likely to drift in a measurement time.

Book Description
Two offset locked frequency stabilized helium neon lasers have been developed for use on the Sub Atomic Measuring Machine's (SAMM) X, Y, and [theta][subscript]z positional feedback interferometers and custom wavelength tracking interferometer. Both utilize a commercially available offset locked iodine stabilized helium neon laser as a frequency reference for offset locked sealed cavity helium neon lasers. The offset locked lasers are housed in hermetically sealed, pressure decoupling chambers providing a high level of passive environmental stability. Actuation of the distance between the offset locked lasers' resonant mirrors is achieved by commercially available 26 [omega] thermofoil heaters with adhesive backing wrapped around the body of the laser tubes. With the use of an AOM and birefringent recombining prism, the positional interferometer offset locked laser system produces a single, 0.9 mW beam with two orthogonal polarization states that differ in frequency by approximately 20 MHz. The positional interferometer offset locked laser system provides more than twice the intensity at 1 mw and an order of magnitude greater frequency stability at 2 parts in 10[superscript]10 (over 72 hours with a frequency gate time of 300 ms) that the previous laser system, a Zygo 7701 laser head. The wavelength tracker offset locked laser has a frequency stability of 4 parts in 10[superscript]10 over 24 hours with a gate time of 300 ms. An optical system designed to divide and launch the reference signal into fibers has also been developed. This dividing platform provides six reference signals directly traceable to the definition of the meter for other offset locked lasers or for long term wavelength comparison of existing stabilized lasers, among other applications, throughout the Center for Precision Metrology.

Book Description
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.
