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 2015-10-14 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines laser generation from the ultraviolet to the short edge of the mid-infrared band by exploiting the nonlinear effects in photonic crystal fibers (PCFs). Several different physical mechanisms are investigated by using homemade PCFs with elaborately customized dispersion profiles. A particular focus is on the development of fiber optical parametric amplifiers (FOPAs) and oscillators (FOPOs) based on the PCFs with a zero-dispersion wavelength of ca.1.06 μm. In particular, several schemes are proposed for solving the key problems involved in the application of FOPOs. These oscillators can be made more convenient to use by optimizing the wavelength-tuning mechanisms and made more energy-efficient with the help of specially designed cavity structures. Today’s oscillators are more reliable, powerful and maneuverable than ever. This thesis provides a systematic road map in connection with the study of nonlinear wavelength generation in PCFs, from their fiber design and technical fabrication, to their physical mechanism and experimental investigation.

Available in PDF, EPUB and Kindle. Book excerpt: The goals of this work are, first, to determine different parameters of rare-earth-doped fibers and glasses and, second, to develop a simulation model for rare-earth-doped fiber lasers and amplifiers in order to avoid time consuming and expensive measurements in the laboratory during the development of such devices. The model should be applicable to arbitrary rare earth devices in a variety of configurations and cover their steady-state and transient behavior. Moreover, cross relaxation processes between two different rare earth ions should be taken into account as it is commonly used for better performance of fiber lasers and amplifiers. For the simulation a couple of spectroscopic parameters are needed, which have to be obtained in advance from bulk glasses. Some parameters like the non-radiative transition rates are difficult to obtain and thus an approach is shown to fix these usually unknown values and to consider thermally coupled energy levels. After a short introduction, which includes general laser theory and an overview of some selected solid-state and semiconductor laser systems, some properties of rare-earth-doped materials and glass hosts are discussed. The focus is Pr3+/Yb3+-doped fluoride glass and the underlying avalanche upconversion process. Then, a coherent reflectometric technique (C-OFDR) is applied to characterize thulium-doped fluoride fiber amplifiers (TDFAs) operating in the S-band of optical communications. The optimum length of the fluoride fiber and quantities like fiber gain and optimum gain-length ratio are determined for ZBLAN fibers with different thulium concentrations. Furthermore, a frequency transfer function (FTF) method is introduced to extract fluorescent lifetimes of energy levels of arbitrary rare-earth-doped glasses and fibers from phases and/or magnitudes of the measured frequency transfer function. This method is applied to measure lifetimes of the upper laser levels of praseodymium-doped fluoride glasses, namely ZBLAN and IBZP. Some of the glass samples are co-doped with ytterbium. These results are reported together with the investigation of the concentration quenching effect. Moreover, spectroscopic results of Pr3+- and Yb3+-doped ZBLAN glasses are presented and included in the simulation model developed. Simulations are carried out for Yb3+-, Pr3+- and Pr3+/Yb3+-doped ZBLAN fiber lasers. Their behavior in stationary and dynamic states is investigated for a simple Fabry-Perot setup. The demonstration of the dominant role of the avalanche upconversion process for Pr3+/Yb3+-doped ZBLAN fiber lasers is shown and the turn-on behavior of the above mentioned lasers shows relaxation oscillations typical to solid-state lasers. With the model at hand it is easily possible to simulate any other laser or amplifier configuration as well.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this work was to develop and investigate fiber lasers emitting in the visible spectral range. We concentrated on the improvement of lasers based on Pr3+/Yb3+-doped fiber. Blue, green, orange and red fiber lasers in different configurations were presented. We started with spectroscopic measurements in which Pr3+-doped ZBLAN and IBZP glass samples were investigated. Comparing the position of absorption peaks in both kinds of glasses, no significant differences were noticeable. However, the emission properties of Pr3+-doped fluoride glasses are dependent on the glass composition. The knowledge gained from spectroscopic measurements was useful to construct fiber lasers based on the Fabry-Perot configuration. This setup allowed us to obtain lasers emitting at 490 nm, 520 nm, and 635 nm. The greatest efficiency was found for a red laser with 20 mW of output power at a pump power of 500 mW. At the same pump power, the green and blue lasers had an output power of 9.3 mW and 4.8 mW, respectively. During this work, optimization of the laser parameters of the red laser was performed. We found that the optimum pump wavelength is approximately 840 nm, and pump wavelength changes of ± 10 nm cause only a small intensity deviation. The influence of mirror reflectivity and the fiber length was also investigated. Another focus of the measurements was the laser output stability. The red laser exhibited a very low noise level, but the output power from the blue laser was very unstable with strong self-pulsing behavior. For the red and green laser, we applied a noise controlling opto-electronic feedback loop, and we observed some reduction in the noise level. We also tested the long-term stability of our lasers over a period of one hour, and no significant decrease of the output power was observed. There are a number of disadvantages of the Fabry-Perot setup; therefore, we examined alternative approaches for all-fiber laser configurations. We constructed a red ring laser in which bulk mirrors are not required. This setup used directional couplers; therefore, some part of this work was dedicated to the manufacturing of these components. Another important component of the ring laser was glue splice which enabled us to connect silica and fluoride fibers. The optimum performance of the red ring laser was measured with an output coupling of 52 %, and we obtained 8 mW output power at 500 mW pump power. Another way to construct an all-fiber laser setup is fiber loop mirror. A laser with these components was also investigated. Because of the broad fluorescence width of the Pr3+ ions, fiber lasers operate in many longitudinal modes. Fiber Bragg gratings have a very narrow reflection bandwidth, and they have been used for narrowing the linewidth of the fiber laser. When a fiber grating was applied, we observed only one longitudinal mode, and the full-width at half-maximum of this laser was only 0.2 nm.
