This book was released on 2005 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulse compression systems for future linear colliders, such as NLC and JLC, involve hundreds of kilometers of waveguide runs. These waveguides are highly overmoded to reduce the rf losses. Reducing the length of these waveguide by loading them with irises increase the losses of the system. Also, loading makes the waveguide depressive, and rf pulse shapes get distorted. In this paper we present a novel idea for utilizing the waveguides several times by using different modes. All the modes being used have low-loss characteristics. We describe mechanically simple mode transducers that switch the propagation mode from one configuration to another with no observable dispersion. We compare our theoretical designs with experimental data.

Download or read book IMPROVED DELAY LINE TECHNIQUES STUDY. written by HUGHES AIRCRAFT CO FULLERTON CALIF. and published by . This book was released on 1965 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dispersive delay lines are a very stable and reliable pulse compression technique. As a result of increased requirements placed on pulse compression systems such as bandwidth, and time-bandwidth products, dispersive delay line techniques must be improved. Improved dispersive delay line technology as applied to pulse compression systems was investigated. Higher frequency of operation, broader bandwidth and greater ease of fabrication were the primary areas of interest. Two dispersive delay line configurations were investigated. The first configuration was a technique based on the dispersive characteristic which results from elastic waves propagating in thin metal strips, and the second configuration was based on slow wave propagation in a yttrium iron garnet. An investigation was undertaken to determine a highly efficient transducer to be used in conjunction with the dispersive delay lines. Vacuum deposited cadmium sulfide transducers proved to be most desirable and successful in constructing delay lines of broad instantaneous bandwidth. (Author).
Book Synopsis Delay Line Investigation by : David E. Flinchbaugh
Download or read book Delay Line Investigation written by David E. Flinchbaugh and published by . This book was released on 1969 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dispersive delay line of the perpendicular diffraction grating type was investigated. The delay line operated at 100 MHz with 40 MHz bandwith and 26.7 microsecond dispersion. One of the program's primary goals was insertion loss reduction. To this end a technique was developed that reduced the insertion loss from 95 db (best previously obtained) to 60 db. A breadboard pulse compression system was fabricated and demonstrated using the delay line. The system exhibited over 1000:1 pulse compression ratio, 35 ns compressed pulse width at the -3 db points, -33.5 db sidelobe level, and 55 db dynamic range. The system is lightweight, compact, and well suited to airborne applications. It is highly probable that the technique is applicable to pulse compression ratios approaching 10000:1. (Author).

Book Synopsis A New Generation of High-Power, Waveform Controlled, Few-Cycle Light Sources by : Marcus Seidel
Download or read book A New Generation of High-Power, Waveform Controlled, Few-Cycle Light Sources written by Marcus Seidel and published by Springer. This book was released on 2019-02-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents first successful experiments to carrier-envelope-phase stabilize a high-power mode-locked thin-disk oscillator and to compress the pulses emitted from this laser to durations of only a few-optical cycles. Moreover, the monograph introduces several methods to achieve power-scalability of compression and stabilization techniques. All experimental approaches are compared in detail and may serve as a guideline for developing high-power waveform controlled, few-cycle light sources which offer tremendous potential to exploit extreme nonlinear optical effects at unprecedentedly high repetition rates and to establish table-top infrared light sources with a unique combination of brilliance and bandwidth. As an example, the realization of a multi-Watt, multi-octave spanning, mid-infrared femtosecond source is described. The thesis starts with a basic introduction to the field of ultrafast laser oscillators. It subsequently presents additional details of previously published research results and establishes a connection between them. It therefore addresses both newcomers to, and experts in the field of high-power ultrafast laser development.

Book Synopsis Femtosecond Optical Frequency Comb: Principle, Operation and Applications by : Jun Ye
Download or read book Femtosecond Optical Frequency Comb: Principle, Operation and Applications written by Jun Ye and published by Springer Science & Business Media. 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.
