Book Description
This text examines the current technology of rare earth doped fibres, the laser sources and amplifiers made with these fibres, and fibre communication systems incorporating erbium-doped fibre amplifiers. The book: covers fibre fabrication techniques, basic spectroscopy and optical properties of rare earth in glasses and analytical models of fibre lasers and amplifiers; describes the main passive fibre components used in the fabrication of more elaborate fibre laser devices and systems; discusses the properties of Nd-doped and Er-doped fibre lasers operated as continuous wave, Q-switched and mode-locked sources; reviews the tunability and single frequency operation of fibre laser sources, as well as broadband fibre sources; includes an extensive review of fibre lasers based on rare earth doped fluoride fibres; and treats the main fibre-based systems using erbium-doped fibre amplifiers that have been demonstrated, including long-haul experimental communication systems and local area networks for TV and computers.

Book Description
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.
