Available in PDF, EPUB and Kindle. Book excerpt: An experimental and theoretical discussion of self-mode locking in multimode CW gas lasers is presented. The average saturated gain profile is assumed to be nearly flat in the frequency range of the oscillating modes because the homogeneous pressure-broadened linewidth is larger than the intermode frequency spacing. For He-Ne and He-Cd(+) lasers the gain fluctuations which occur as the pulses propagate through the active medium are believed to be small since the pulse velocity has been found to be approximately the same as the group velocity associated with the average dispersion. Estimates of the recovery time for the inversion density in a He-Ne laser indicate that the gain variations are a few percent of the average gain. An experimental technique for measuring the mode phases was developed, and measurements were made on a self-locked He-Ne laser with about seven modes. The results show that the modes are not in phase, and that, for the particular laser used, one mode toward the high-frequency end of the spectrum is lagging the others in phase by about 40 degrees.

Download or read book Theory of Self Locking of Lasers with Inhomogeneously Broadened Lines written by R. J. Collins and published by . This book was released on 1973 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical model is given to describe self-locking. The semi-classical theory of Lamb for laser action has been modified to include the collisional effects on linewidth and on the nonlinear polarization. The collisional effects were included by a classical atom-atom rate. The results modify Lamb's equation for the frequencies and phases of oscillating modes. The criterion of self-locking of modes is expressed in terms of ratio of loss to unsaturated gain. Comparisons of the theoretical results and published experimental results for He-Ne and He-Cd are satisfactory. (Author).
Download or read book Lasers and Electro optics written by Christopher C. Davis and published by Cambridge University Press. This book was released on 2014-03-20 with total page 887 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering a broad range of topics in modern optical physics and engineering, this textbook is invaluable for undergraduate students studying laser physics, optoelectronics, photonics, applied optics and optical engineering. This new edition has been re-organized, and now covers many new topics such as the optics of stratified media, quantum well lasers and modulators, free electron lasers, diode-pumped solid state and gas lasers, imaging and non-imaging optical systems, squeezed light, periodic poling in nonlinear media, very short pulse lasers and new applications of lasers. The textbook gives a detailed introduction to the basic physics and engineering of lasers, as well as covering the design and operational principles of a wide range of optical systems and electro-optic devices. It features full details of important derivations and results, and provides many practical examples of the design, construction and performance characteristics of different types of lasers and electro-optic devices.

Download or read book Fiber Lasers written by Liang Dong and published by CRC Press. This book was released on 2016-09-19 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous development in the past decade or so, transforming itself from a research curiosity to a major force in modern manufacturing. Today, it is revolutionizing our economy by fundamentally changing the way we mark, machine, and process materials on an industrial scale. The recent development of high-power fiber lasers is also fundamentally shaping a wide range of other areas from physical sciences and medicine to geology and space exploration. In the past few years, the tactical deployment of direct energy weapons based on fiber lasers has become a reality. The development of fiber lasers is rooted in a number of technical areas including optical materials, optical waveguide design, nonlinear optics, optical fiber fabrication, and optical characterization, in addition to optical fiber components, and fiber laser design and architecture. No comprehensive in-depth coverage of such diverse topical areas has appeared in a single book. Many important developments have taken place in the past decade in both academia and industry. This book comprehensively covers the basics, technology and applications of fiber lasers including up-to-date developments in both academia and industry and is aimed to serve as both an introduction and research aid for graduate students, engineers, and scientists who are new to this field and also for veterans in the field

Download or read book Solid State Laser Engineering written by Walter Koechner and published by Springer. This book was released on 2013-11-11 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, written from an industrial vantage point, provides a detailed discussion of solid-state Iasers, tbeir characteristics, design and construction, and practical problems. The title Solid-State Laser Engineering has been chosen because tbe emphasis is placed on engineering and practical considerations of solid-state Iasers. I have tried to enhance tbe description of the engineering aspects of Iaser construction and operation by including numerical and technical data, tables, and curves. The book is mainly intended for tbe practicing scientist or engineer who is interested in tbe design or use of solid-state Iasers, but tbe response from readers has shown tbat tbe comprehensive treatment of the subject makes tbe work useful also to students of Iaser physics who want to supplement tbeir tbeoretical knowledge witb tbe engineering aspects of Iasers. Although not written in the of a college textbook, tbe book might be used in an advanced college course form on Iaser technology. The aim was to present the subject as clearly as possible. Phenomenological descriptions using models were preferred to an abstract matbematical presenta tion, even tbough many simplifications bad tben to be accepted. Results are given in most cases witbout proof since I have tried to stress tbe application of tbe results rather than the derivation of the formulas. An extensive Iist of references is cited for each chapter to permit tbe interested reader to learn more about a particular subject.
