This book was released on 1995 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for building an optical to microwave frequency chain and for measuring optical frequencies relative to the cesium primary frequency standard is described. Based on optical frequency division via parametric oscillators, the concept is to generate two known ratios (1/2 and 4/9) of an optical calibration frequency f1 whose frequency difference is measured relative to the cesium clock. The (1/2) ratio is obtained by either a 2:1 frequency division of f1 or second-harmonic generation of (1/2) f1. The (4/9) ratio of f1 can be generated with a 3:1 frequency divider driven by a second laser at f2 that is chosen to be near (2/3)f1, which in turn is obtained with a f1-pumped 3:1 frequency divider. A set of auxiliary Optical Parametric Oscillators (OPOs) with outputs centered at (1/2)fi is used to facilitate the difference-frequency measurement between the two ratios. A practical configuration utilizing a YAG and a Ti: A12O3 laser and its application to a number of precision measurements of interest are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear optical techniques have been evaluated for the conversion of out-of-band diode laser radiation into the 2- to 5- micrometers region, It is concluded that frequency conversion using an optical parametric oscillator is the preferred nonlinear approach and that ZnGeP2 is the most promising nonlinear material. Direct diode or diode array pumping of the nonlinear material may require semiconductor laser operation in the 1.7- to 2.0 micrometers region and will entail substantial increases in the peak power and beam quality in comparison to that obtainable from present devices. Diodes pumped solid state lasers might provide a reasonable near-term solution to the pump source requirements.

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.

After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards from atomic clocks, to frequency stabilised lasers.
