Available in PDF, EPUB and Kindle. Book excerpt: We have pursued a vigorous program of experimental and theoretical research on a novel method of frequency division based on an optical parametric oscillator (OPO). We have successfully demonstrated optical frequency division in a nearly degenerate KTP OPO that is highly efficient and tunable. The difference frequency of the two subharmonic outputs of the OPO was phase locked to a 12-GHz microwave source with a residual phase noise spectral density of 0.3 mrad/VH-z. More recently the use of a THz optical frequency comb permitted the OPO to be phase locked at a difference frequency of 665 GHz. We have studied a number of potential applications including optical frequency counting for frequency standards and multi-THz optical frequency comb generation for optical communications.

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.

Download or read book Optical Frequency Division by 3 Employing Self phase locking in Periodically Poled Lithium Niobate written by Pavel Vladimir Gorelik and published by . This book was released on 2005 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: A. method used to obtain frequencies in precise ratios of 2/3 and 1/3 of the pump is described as a possible way to extend the usable range of octave-spanning optical frequency combs for frequency metrology applications. The divider is based on a self- phase locked optical parametric oscillation in a doubly resonant semi-monolithic optical cavity containing a dual-grating periodically poled lithium niobate. The design, implementation and evaluation of such a frequency divider are described. Preliminary experimental data from the self-phase locked optical frequency divider is presented. We have obtained sub-100 mW threshold for the optical parametric oscillator with stable operation over 1 s without servo locking the cavity length. Preliminary results suggest that self-phase locking has been observed.

Available in PDF, EPUB and Kindle. Book excerpt: This work reviews the principles underlying quantum-based atomic clocks, with introductory chapters placing them in context with the development of mechanical clocks and electronic quartz-controlled clocks. The book details design principles of the rubidium, cesium, hydrogen maser, and mercury ion standards; changes enabled by the advent of the laser; and the time-based global navigation systems, Loran-C and the Global Positioning System. The new edition includes such recent developments as clocks based on quantum resonance at optical frequency in individual ions confined in miniature electromagnetic traps. The Quantum Beat explores the subject with a minimum of mathematical formalism.
