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: 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: 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

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 2013 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond fiber lasers have become an important enabling technology for advances in many areas including: frequency combs, precise timing distribution, optical arbitrary waveform generation, and high bit rate sampling for analog to digital conversion. Experiments and applications like these put demanding requirements on the source laser oscillator; such as operating near 1550 nm in wavelength, multi-gigahertz repetition rates, sub 100 femtosecond pulse widths, and sub 10 femtosecond timing jitters. This thesis describes the design, fabrication, and characterization of three different iterations of mode-locked laser sources utilizing erbium doped fibers and semiconductor saturable absorbing mirrors to form pulse trains in the 1550 nm wavelength band. The first systems took advantage of a highly doped erbium fiber in a sigma cavity configuration to generate 100 fs pulses at up to a 300 MHz repetition rate through polarization additive pulse mode-locking. At the time, this was the highest fundamental repetition rate to be reported for a fiber cavity in a ring configuration. The next two systems are variations on a linear cavity fiber laser design. In the first, the fiber coupling was achieved through free space optics and the saturable absorbing mirror was also imaged through lenses. Once mode-locked, repetition rates of just beyond 1 GHz were demonstrated with this design; however the laser output was relatively low power. The second version coupled the input and output light through fiber components and coupled the fiber directly to the saturable absorbing mirror. This laser mode-locked in several different states and a study to characterize and understand these states was undertaken. Ultimately, it was understood which conditions minimized the cavity noise and pulse widths thus allowing for the achievement of a 1550 nm, 1 GHz, sub 10 fs jitter, femtosecond fiber laser. This laser is more compact than competing technologies and could be constructed with relatively low cost.
