This book was released on 2008 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in fully-stabilized mode-locked laser systems are enabling many applications, including optical arbitrary waveform generation (OAWG). In this thesis work, we describe the development of high repetition-rate fiber laser-based systems for the realization of these applications at 1550 nm wavelengths. To realize these systems, frequency comb sources are needed that are compatible with electric field stabilization techniques, are compatible with integrated arrayed waveguide grating and modulator technology, and have high repetition rates to allow full use of current modulator bandwidths. Erbium-doped fiber lasers are one of the leading options to fill this role. To that end, fundamentally mode-locked stretched pulse fiber lasers approaching 250 MHz repetition rate and soliton fiber lasers at over 200 MHz repetition rates are presented, and the limitations of repetition rate scaling in fiber lasers are explored. Using the 200 MHz soliton laser and an external Fabry-Perot cavity, a low-noise, repetition rate multiplied 2 GHz source is demonstrated. Stabilization systems for high repetition rate sources must also be developed. Carrier envelope offset locking experiments using self-referencing techniques at 200 MHz repetition rate are described. Initial demonstrations towards repetition rate locking to a methane-stabilized HeNe single-frequency standard using difference-frequency generation are presented.

Download or read book Passively Mode locked Erbium doped Fiber Lasers Using Multiple Quantum Well Saturable Absorbers written by Michael Joseph Hayduk and published by . This book was released on 1997 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of the mode-locking process in erbium-doped fiber lasers (EDFL's) operating at 1.55 microns using multiple quantum well saturable absorbers is presented. The self-starting passively mode-locked laser was constructed in a Fabry-Perot configuration using the saturable absorber as the back reflector of the cavity. Picosecond pulses that range from 14.2 to 38.8 ps were generated using a series of saturable absorbers. The pulse widths were dependent upon the optical properties of the saturable absorber used as the mode-locking element. The output power of the EDFL varied from 0.2 to 6.7 mW and was also dependent upon the saturable absorber used in the cavity. Soliton mode-locking using saturable absorbers was the mechanism responsible for the generation of the picosecond pulses by the EDFL. The long-lived carrier lifetime in the quantum wells was the primary optical property of the saturable shorter that determined the final pulse width.

Book excerpt: This handbook provides a comprehensive review of the entire field of laser micro and nano processing, including not only a detailed introduction to individual laser processing techniques but also the fundamentals of laser-matter interaction and lasers, optics, equipment, diagnostics, as well as monitoring and measurement techniques for laser processing. Consisting of 11 sections, each composed of 4 to 6 chapters written by leading experts in the relevant field. Each main part of the handbook is supervised by its own part editor(s) so that high-quality content as well as completeness are assured. The book provides essential scientific and technical information to researchers and engineers already working in the field as well as students and young scientists planning to work in the area in the future. Lasers found application in materials processing practically since their invention in 1960, and are currently used widely in manufacturing. The main driving force behind this fact is that the lasers can provide unique solutions in material processing with high quality, high efficiency, high flexibility, high resolution, versatility and low environmental load. Macro-processing based on thermal process using infrared lasers such as CO2 lasers has been the mainstream in the early stages, while research and development of micro- and nano-processing are becoming increasingly more active as short wavelength and/or short pulse width lasers have been developed. In particular, recent advances in ultrafast lasers have opened up a new avenue to laser material processing due to the capabilities of ultrahigh precision micro- and nanofabrication of diverse materials. This handbook is the first book covering the basics, the state-of-the-art and important applications of the dynamic and rapidly expanding discipline of laser micro- and nanoengineering. This comprehensive source makes readers familiar with a broad spectrum of approaches to solve all relevant problems in science and technology. This handbook is the ultimate desk reference for all people working in the field.

Book excerpt: This thesis reports work in high repetition rate femtosecond fiber lasers. Driven by the applications including optical arbitrary waveform generation, high speed optical sampling, frequency metrology, and timing and frequency distribution via fiber links, low noise fiber laser sources operating at multi-gigahertz repetition rates are developed systematically. A 200 MHz fundamentally mode-locked soliton laser and a 200 MHz fundamentally mode-locked similariton laser are first developed. Intra-cavity soliton formation is recognized as the optimum route towards achieving high fundamental repetition rates compact lasers, under the limitation of realistically available pump power. A 3 GHz fundamentally mode-locked femtosecond fiber laser is developed and verifies the soliton formation theory. Techniques in external cavity repetition rate multiplications are also discussed. A theoretical model that relates the repetition rate of the soliton laser and its other physical measurable parameters is developed to guide further high repetition rate laser development.

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.

Download or read book Ceramic Lasers written by Akio Ikesue and published by Cambridge University Press. This book was released on 2013-05-23 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, ceramic materials were considered unsuitable for optics due to the numerous scattering sources, such as grain boundaries and residual pores. However, in the 1990s the technology to generate a coherent beam from ceramic materials was developed, and a highly efficient laser oscillation was realized. In the future, the technology derived from the development of the ceramic laser could be used to develop new functional passive and active optics. Co-authored by one of the pioneers of this field, the book describes the fabrication technology and theoretical characterization of ceramic material properties. It describes novel types of solid lasers and other optics using ceramic materials to demonstrate the application of ceramic gain media in the generation of coherent beams and light amplification. This is an invaluable guide for physicists, materials scientists and engineers working on laser ceramics.
