Download or read book High Repetition Rate Mode locked Erbium doped Fiber Lasers with Complete Electric Field Control written by Jason William Sickler and published by . 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.

Book excerpt: Mid-infrared gas laser technology promises to become a unique tool for research in strong-field relativistic physics. The degree to which physics is relativistic is determined by a ponderomotive potential. At a given intensity, a 10[micro]m wavelength CO[sub 2] laser reaches a 100 times higher ponderomotive potential than the 1[micro]m wavelength solid state lasers. Thus, we can expect a proportional increase in the throughput of such processes as laser acceleration, x-ray production, etc. These arguments have been confirmed in proof-of-principle Thomson scattering and laser acceleration experiments conducted at BNL and UCLA where the first terawatt-class CO[sub 2] lasers are in operation. Further more, proposals for the 100 TW, 100 fs CO[sub 2] lasers based on frequency-chirped pulse amplification have been conceived. Such lasers can produce physical effects equivalent to a hypothetical multi-petawatt solid state laser. Ultra-fast mid-infrared lasers will open new routes to the next generation electron and ion accelerators, ultra-bright monochromatic femtosecond x-ray and gamma sources, allow to attempt the study of Hawking-Unruh radiation, and explore relativistic aspects of laser-matter interactions. We review the present status and experiments with terawatt-class CO[sub 2] lasers, sub-petawatt projects, and prospective applications in strong-field science.

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 Mid Infrared Fiber Laser Based on Super Continuum written by and published by . This book was released on 2007 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of the Phase I Supplement was to improve the performance of the bench-top, mid-infrared fiber laser system that had been developed under the Phase I program. The program succeeded in demonstrating an all-fiber integrated Mid-InfraRed Fiber Laser (MIRFIL), see Figure 1, with no optical bench, such that bulk optics are no longer required. More specifically, the all-fiber integrated MIRFIL breadboard generates super-continuum (SC) with 1.2W time-averaged power extending to -3.4 microns in 60m of ZBLAN fiber. The long wavelength edge of the SC is limited by the bend-induced loss of the particular ZBLAN fiber used in the experiments. The power levels and repetition have been optimized to generate high time-averaged power along with the broadest spectrum supported by the fiber. In addition, the results from the all-fiber integrated MIRFIL are compared with results obtained using the same ZBLAN fiber in a bulk-optical, tabletop, set-up in Prof. Almantas Galvaunaskas's lab, and the results lay almost directly on top of each other. In order to broaden the spectrum out to -4.6 microns, new ZBLAN fibers with less bend-induced loss will be required, and we are working with fiber makers to fabricate this fiber while maintaining a high damage threshold. One of the first tasks was to implement and characterize the first stage pre-amplifier. The pulse repetition rate in the pre-amplifier can be varied from 20kHz to 500kHz, and the power is scaled up by increasing the repetition rate.

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.

Book excerpt: Ultrashort pulses in mode-locked lasers are receiving focused attention from researchers looking to apply them in a variety of fields, from optical clock technology to measurements of the fundamental constants of nature and ultrahigh-speed optical communications. Ultrashort pulses are especially important for the next generation of ultrahigh-speed optical systems and networks operating at 100 Gbps per carrier. Ultra Fast Fiber Lasers: Principles and Applications with MATLAB® Models is a self-contained reference for engineers and others in the fields of applied photonics and optical communications. Covering both fundamentals and advanced research, this book includes both theoretical and experimental results. MATLAB files are included to provide a basic grounding in the simulation of the generation of short pulses and the propagation or circulation around nonlinear fiber rings. With its unique and extensive content, this volume— Covers fundamental principles involved in the generation of ultrashort pulses employing fiber ring lasers, particularly those that incorporate active optical modulators of amplitude or phase types Presents experimental techniques for the generation, detection, and characterization of ultrashort pulse sequences derived from several current schemes Describes the multiplication of ultrashort pulse sequences using the Talbot diffraction effects in the time domain via the use of highly dispersive media Discusses developments of multiple short pulses in the form of solitons binding together by phase states Elucidates the generation of short pulse sequences and multiple wavelength channels from a single fiber laser The most practical short pulse sources are always found in the form of guided wave photonic structures. This minimizes problems with alignment and eases coupling into fiber transmission systems. In meeting these requirements, fiber ring lasers operating in active mode serve well as suitable ultrashort pulse sources. It is only a matter of time before scientists building on this research develop the practical and easy-to-use applications that will make ultrahigh-speed optical systems universally available.

This book was released on 2012 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond lasers and the development of frequency combs have revolutionized multiple fields like metrology, spectroscopy, medical diagnostics and optical communications. However, to enable wider adoption of the technology and new applications like photonic sampling, optical arbitrary waveform generation or the calibration of astronomical spectrographs, multi-GHz repetition rate femtosecond lasers with robust performance metrics, low cost, and a compact footprint are highly desirable. In this thesis, different approaches to develop GHz mode-locked laser systems at telecommunication wavelengths are discussed and current achievements presented. Design aspects for constructing a long-term stable and compact fiber laser with 187 fs short pulses at a repetition rate of 1 GHz are covered. In order to scale the repetition rate into the multi- GHz regime, coherent pulse interleaving in novel thermally tunable waveguide interleavers is demonstrated at 10 GHz. A femtosecond erbium-doped waveguide laser is developed at GHz repetition rates and important design guidelines are provided. As saturable Bragg reflectors are crucial in all of the described systems to enable mode-locking, saturable absorber optimization is discussed and their optical performance compared. Thus, this research paves the way for compact, affordable high repetition rate fiber lasers and monolithically integrated femtosecond laser sources which can be combined on-chip with additional functionalities to develop novel photonic systems with impact on spectroscopy, sensing, telecommunications and biomedical applications.

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.
