In this research, the performance of thulium-doped fiber lasers is analyzed and a mathematical model is established. Thulium-doped fiber amplifiers are the focus of this article. A large number of simulations have been carried out in the MATLAB simulation environment, and the main work and innovation points are as follows: firstly, the energy level structure characteristics of thulium were studied, and its spectral characteristics were analyzed. After consulting some information, 3H4 to 3H6 energy level has been selected in modeling. Secondly, use the rate equations and the power propagation equations to provide a theoretical analysis of the pumping mode of thulium-doped fiber lasers. And a mathematical model of a thulium-doped fiber laser was established. The parameters such as fiber length and doping concentration in the model are discussed. Finally, to find the appropriate parameters, the genetic optimization algorithm is used to optimize the fiber length and doping concentration, and then we can get the parameters corresponding to the maximum output power of the thulium-doped fiber amplifier.

SummaryOver the past ten years endoveous treatment options for varicose veins have evovled considerably, offering clinicians a multitude of options to meet the needs of their patients. The endothermal ablation procedures have moved to the forefront as the choice modality for treating truncal reflux. Both radiofrequency ablation and endovenous laser ablation are widely accepted and interchangeable, showing comparable efficacy and safety. Although numerous endovenous laser wavelengths exist, the data indicates that the differences do not affect the efficacy or postoperative recovery of the procedure. The endovenous laser innovation that has shown early evidence of improved patient outcome is the jacket-tip fiber. The versatility of sclerotherapy makes it a critical component in the endovenous treatment of varicosities. Although not approved by the Food and Drug Administration (USA), the use of a foamed sclerosing agent is the fastest growing segment of sclerotherapy and an important treatment modality in the future of varicose vein treatment. Cutaneous lasers and intense pulse light devices contribute a crucial element, enabling clinicians to treat minute veins that may be impossible to treat with other therapies.

The thulium-doped fiber amplifier stands out as the most promising amplifier within the S-band spectrum. This paper delves into the exploration of a 1.47um Tm^(3+)-doped fluorinated fiber amplifier as the primary subject of research. This paper approach begins by establishing the rate equation and power propagation equation for the thulium ion level structure, followed by rigorous mathematical analysis and solutions. Subsequently, we employ MATLAB programming to perform comprehensive calculations, scrutinizing the amplified spontaneous emission spectra's variation concerning Thulium-Doped Fiber Amplifier (TDFA) length and pump power. In a quest for optimal performance, this paper turn to the simulated annealing algorithm to fine-tune the doping concentration and fiber length, ultimately achieving the most favorable output spectral gain. Through systematic experimentation and parameter manipulation, we've unveiled a substantial breakthrough, with our research yielding an impressive optimal gain of 31.71 dB. The ramifications of this work extend far beyond the confines of this study. It sets a solid foundation for advancements in fiber fabrication and paves the way for the realization of fiber lasers, promising significant contributions to the expansion of S-band fiber communication systems. Our findings hold great promise and are poised to drive innovation in this critical area of telecommunications.

Les travaux présentés dans ce manuscrit s’inscrivent dans le cadre d’une thèse CIFRE en colla-boration entre le laboratoire Xlim et le centre technologique optique & lasers « ALPhANOV ». L’objectif principal de cette thèse consiste à développer des préformes dopées à l’ytterbium, conçues pour résister au phénomène de photo-noircissement (PN), en vue de leur utilisation dans des applications laser à haute puissance. Ce phénomène dégrade les performances des lasers et entraîne une réduction de leur puissance de sortie. Les travaux de cette thèse sont articulés autour de deux principaux axes. Le premier vise à définir la composition du cœur ainsi que la méthode de synthèse appropriée pour fabriquer des cœurs de préformes résistant face au photo-noircissement (PN). Le deuxième axe repose sur l’élaboration, la caractérisation et l’évaluation des performances optiques de la fibre obtenue. La matrice choisie pour être étudiée est la matrice alumino-phosphosilicate. Elle a été obtenue par une méthode de synthèse appelée « poudre en suspension ». Les différentes étapes de ce procédé de fabrication ont été validées depuis la synthèse de la préforme jusqu’à l’étirage de la fibre optique. Les tests optiques effectués sur la fibre optique ont révélé d’excellentes performances, avec une faible atténuation de 0.1 dB/m et une efficacité de conversion optique- optique très prometteuse de 76 %. L’évaluation de cette fibre face au phénomène de photo- noircissement a révélé une résistance exceptionnelle. Aucune décroissance en puissance n’a pu être constatée au cours des expériences effectuées sur plus de 100 h
The work presented in this manuscript is part of a PhD thesis carried out by CIFRE in collabora-tion between the laboratory of Xlim and the technological center of optics and lasers "ALPhA-NOV". The main objective of this thesis is to design ytterbium doped preforms that are resistant to the photodarkening (PD) phenomenon for use in high power laser applications.This phenomenon degrades laser performance and leads to reduced output. Two main areas are focused in this thesis. The first is the definition of the core composition and the appropriate synthesis method for the production of preform cores which are resistant to photodarkening (PD). The second is to develop, characterize and evaluate the optical performance of the resulting fiber. The matrix that has been chosen for the study is the alumino-phosphosilicate matrix. To obtain this matrix, a synthesis method called "powder in suspension" was used.From the synthesis of the preform to the drawing of the optical fiber, the different stages of the process have been validated. Excellent performance, with low attenuation of 0.1 dB/m and a very promising optical-to-optical conversion efficiency of 76%, was obtained from the optical tests performed on the fiber. The evaluation of the fiber against photodarkening showed an exceptional resistance. No performance degradation was observed over 100 hours

This thesis reports on the experimental study of high-power, high-energy, cladding-pumped, rare-earth (Yb3+, Er3+/Yb3+)-doped fibre lasers. Some of the main capabilities of fibre lasers such as: High brightness and thermal properties were exploited for the development of a variety of continuous wave (CW) and Q-switched devices, whose characteristics also includes compactness. Our devices could already be considered an option for several applications. The 25-year long scientific and commercial evolution that fibre lasers have experienced is discussed in the first two chapters. The invention of Erbium-doped fibre amplifiers (EDFA's) and Internet were two major breakthroughs, which launched the need of WDM systems and laser sources. Fibre lasers, are now considered a flexible and powerful device whose technology has finally reached its maturity. Cladding pumping is the technique employed in these experiments in order to pump double clad fibre lasers using high power, broad stripes and bars. In this work, several inner cladding shapes have been used to overcome the normally high mismatch between diode laser beams and inner cladding areas of fibre lasers. Chapter Three consists of a review of cladding-pumped fibre lasers. It describes how inner cladding geometry and pump absorption limits the output power scalability of these devices. Nonlinear effects and amplified spontaneous emission are also studied due to their implication they have over fibre lasers performance. Results on conventional, continuous wave (CW) fibre lasers including fibre characterization and employed launching techniques are described in Chapter Four. A new method to obtain high intensity laser beam output from an Yb3+-doped, cladding-pumped, highly multimode fibre laser has been proposed. In this experiment, we propose the use of fibre tapers to increase intensity and improve beam quality. In CW regime, our results show an intensity increase of ~3.5 times with a low power penalty of ~1 dB. Also, without tapering, a maximum output power of 21-W was reached with a slope efficiency of >80%. Using a simple set of optic elements such as a l/2 waveplate, a polarizing beam-splitter and a bulk grating, we investigated the polarization characteristics of an Yb3+ fibre laser, from which we obtained 6.5 W of single polarization tunable output in the range of 1070 to 1106 nm. As a free running laser, the system produced 18 W at 1090 nm and showed a threshold of 1.8 Watts. The experiment is our first approach for developing a reliable high-power Yb3+-doped fibre source, that could be used in conjunction with optical parametric oscillators (OPO) and amplifiers (OPA) to frequency convert to a broad band of wavelengths. Using a new design of ytterbium-doped fibre made in-house with the conventional modified chemical vapor deposition (MCVD) process, we explored the possibilities of energy storage with such a large mode area (LMA) fibre. The fibre system was capable of delivering energetic pulses of >2 mJ, which could suggest the feasibility of a pulsed fibre laser in the region of tens of milli-Joules. The experiment is described in Chapter Six, on which the experiment that uses the tapered fibre laser in Q-Switched regime is also described and compared to LMA fibre laser. Gaussian-type pulses were obtained which reached pulse energies of 0.6 mJ at 4 kHz using a tapered fibre laser and 1.3 mJ at 500 Hz using conventional laser, corresponding to average powers of 2.1 Watts for the tapered laser and 0.8 watts for the conventional laser. Er3+/Yb3+-doped fibre lasers were part of our experimental work. This co-doping technique allows pumping of Yb3+ ions using broad-stripe high-power pump sources to reach much higher output power levels. Efficient energy transfer from excited Ytterbium ions into Erbium is achieved. From a preliminary study, the fibre laser showed a threshold of 160 mW and a slope efficiency of 49% with respect to absorbed pump power. The maximum output power was 6.2 watts at 1535 nm and a linewidth of 1 nm. One of our co-doped fibre devices produced 16.8 W of continuous wave, multimode laser power at the interesting wavelength of operation of 1550 nm. Finally, conclusions and future work are included in Chapter Eight.

Ces travaux de thèse s’inscrivent dans une collaboration long-terme entre le laboratoire Xlim et l’entreprise EOLITE Systems dans le but de développer de nouvelles fibres optiques à très grande aire modale typiquement capables de délivrer une puissance moyenne supérieure à 200 W et une puissance crête de l’ordre de 1 MW avec une émission monomode transverse à 1030 nm. Pour cela, des fibres optiques à microstructuration apériodique (FA-LPF) ont été développées en vue d’améliorer les performances des fibres commerciales, en repoussant en particulier le seuil des instabilités modales transverses. Une étude expérimentale sans précédents a été menée pour mettre en évidence l’influence de la structure de la fibre, de l’architecture de la source et du diamètre de champ modal sur le seuil d’apparition du phénomène. Par ailleurs, la fibre commerciale a été remplacée par une FA-LPF dans un prototype laser industriel, et a donné lieu à une validation de principe, tant du point de vue des performances pures que du vieillissement. La faisabilité d’une fibre micro-structurée courte et efficace (de 50 cm de long), a également été étudiée, en passant par une augmentation de la concentration en ions ytterbium dans le coeur de la FA-LPF ou encore par l’amélioration du ratio coeur/gaine. Finalement, un concept de fibre à coeur enterré a permis d’atteindre des dimensions de coeur supérieures à 110 μm tout en maintenant une émission monomode transverse
These Ph.D work is conducted in the context of a long-term collaboration between Xlim laboratory and the company EOLITE Systems in order to develop new large mode area fibers typically capable of providing up to 200 W of average output power and a peak power of 1 MW while maintaining a transverse single-mode emission at 1030 nm. For that purpose, optical fibers with an aperiodic microstructuration (FA-LPF) were developed in order to improve the performances of commercial fibers, mainly by pushing further the transverse mode instabilities power threshold. An unprecedented experimental study has been conducted to investigate the influence of the fiber structure, the laser source architecture and the mode field diameter. Furthermore, by replacing the commercial fiber by a FA-LPF in an industrial laser prototype, as a proof-of-concept, the FA-LPF permits to obtain a laser source with at least similar properties as those of the laser sources of the company regarding the laser efficiency or the lifetime test. The feasibility of a microstructured fiber shorter and still efficient (50 cm-long), has also been studied, by increasing the ytterbium ions concentration in the FA-LPF core or by improving the core to clad ratio. Finally, a new concept of fiber with a depressed-index core led to core diameters higher than 110 μm while maintaining a transverse single-mode emission

Single-mode fibre lasers are a new class of active fibre device, which play a remarkable role in optical fibre communications and sensors. They also exhibit a number of new phenomena, one of the most important being polarisation effects. In this thesis, new unexpected fundamental polarisation effects in fibre lasers have been discovered. The phenomena are fluorescence depolarisation, the existence of orthogonal polarisation eigenmodes, and the dependence of the output polarisation on the pump polarisation state. A unified theoretical model, incorporating the electric dipole model for rare-earth ions in a glass matrix, is formulated. The concept of effective pump power is introduced and can be applied to existing laser theory; thus laser performance characteristics such as thresholds, slope efficiencies and the polarisation state of the output can be predicted accurately. The good agreement between theory and experiment enables the derivation of the polarised cross-section ratio. This has been done for Nd3+ and Er3+ ions in silica fibres. From the theoretical analysis the optimum condition for single polarisation operation is deduced. An effective technique for making single-polarisation single-mode (SPSM) fibre lasers has been developed using an integral fibre polariser. The advantages of this technique are low insertion loss, high polarisation extinction ratio and compatibility with existing single-mode fibre components. Laser-diode-pumped SPSM fibres of high performance, both in continuous-wave and Q-switched operations, have been achieved.

This thesis describes the development and characterisation of single-mode optical fibre lasers and amplifiers. Although the fibre laser configuration was first employed over twenty years ago, its application to conventional optical fibre technology has not been demonstrated previously. The new devices are based on single-mode fibres doped with rare-earth ions, notably neodymium and erbium. The combination of strong absorption bands, long fluorescence lifetimes; low fibre losses in the infra-red and small fibre cores have made possible very low threshold and efficient fibre lasers. Experiments on the tunability, output spectra and pulsed operation of these devices are described. A number of world firsts, including the Lowest, threshold and widest tuning range of a doped glass laser, and the efficient CW operation of an erbium-doped three level laser, have been achieved. High-gain amplification at 1.54µm, the preferred wavelength for optical communication, has also been demonstrated. The results have been modelled by adapting conventional laser theory to the single-mode fibre configuration, and some simple design criteria are considered.

Laser light has enabled some of the most important scientific discoveries and innovations, and research in newer types of lasers continues to reveal more applications. Mid-infrared light, which interacts strongly with naturally occurring molecules, holds many promises in sensing and medical technologies and their applications are now beginning to appear. This surging development will strongly benefit with the availability of field-usable, compact and robust sources of mid-infrared light. The fibre lasers have the extreme potential to achieve this; however their performance in terms of generating ultrafast pulses of mid-infrared light has not yet been demonstrated. Here we explore the potential fluoride fibre lasers have in the ultrafast pulsed regime. We have demonstrated this via the production of nanosecond, to picosecond, and finally femtosecond pulses from fluoride fibre lasers using a variety of methods. These demonstrations reveal that fluoride fibres lasers are strong candidates to be an ultrafast mid-infrared source, with applications ranging from frequency comb based molecular sensing to next generation laser scalpels.

We present an ultrafast laser fabricated end-cap for use with polymer imaging fibres. The end-cap enables optical sectioning of the imaged sample and reduces back-ground fluorescence from both the sample and the fibre itself.

This master thesis explores the challenges for waste management business models in the field of textiles regarding the requirements of the circular economy, as well as improvement potentials in the current framework conditions. It is concerned with the research question: "Is it advisable to change the frame-work conditions at meso or macro level, with regard to business models for waste management companies in the textile sector that are oriented towards the requirements of the circular economy, and - if so - in what way?” The approach of the study is based on the delta analysis of the e Society for Institutional Analysis at the Darmstadt University of Applied Sciences. It compares the target state of the normative requirements with the actual state of the textile and waste management framework conditions and attempts to identify the gaps (the delta). Based on the delta, it develops approaches that are intended to help reduce the gaps. The thesis develops three business models for the target year 2025 in different areas: an exchange platform for sorters, recyclers and designers, an automatic sorting plant and a plant for fibre-to-fibre recycling of mixed materials. It is becoming clear that these business models cannot meet the target requirements for the circular economy. The analysis identifies the remaining gaps in the framework conditions as the main problem. For example, insufficient innovation impulses and the lack of competitiveness of secondary raw materials inhibit the actors from applying and using new technologies and business models. Restricted access to knowledge and information, as well as a lack of transparency between the actors, also prove to be problematic. In order to answer the research question, the study recommends altering the framework conditions at meso and macro level. It proposes a platform for cooperation between designers, the introduction of a material declaration system and an eco-design guideline for textiles as possible development options. In addition, this work offers a matrix of criteria to help the actors test and improve their new waste management business models regarding their suitability for the circular economy. The analysis is carried out from an outsider's perspective on the entire textile industry. It therefore cannot cover and deal with all aspects and individual circumstances of each player in detail. The necessary changes in the framework conditions that have been identified can therefore be used as a basis for further investigations.
