Masterarbeit aus dem Jahr 2013 im Fachbereich Physik - Optik, Note: 1.3, Ludwig-Maximilians-Universität München, Sprache: Deutsch, Abstract: With the prospect of high-intensity isolated attosecond pulses XUV pump-XUV probe spectroscopy as well as novel methods for controlling atomic-scale currents seem feasible paving the way for new physical, chemical, biological, and medical applications such as attosecond X-ray diffraction, non-invasive imaging and cancer therapy. To reach these ambitious goals, optical parametric chirped pulse amplifcation (OPCPA) in combination with high harmonic generation (HHG) seems like a promising route. But this approach puts stringent demands on the pump laser driving it. To overcome these challenges Yb:YAG as active laser medium in a thin-disk geometry is often used offering a lot of favourable properties for high power applications with excellent beam quality. Yb:Yag can be pumped at either 940 nm or, more recently, since the advent of Volume-Bragg-Grating stabilized diodes, at its Zero-Phonon-Line with a wavelength of 969 nm. These two wavelengths excite different transitions in the 5 F 1/2 electronic shell each exhibiting its own assets and drawbacks. This thesis will focus on a comparison between them. A theoretical model of the conditions in the pumped thin-disk is created. Absorption of the pump light is calculated numerically. Amplified spontaneous emission and thermal effects are considered, too. The structure of the 5 F 1/2 energy manifold is accounted for thus allowing predictions for two different pumping wavelengths at 940 nm and 969 nm. To gauge the accuracy of the model the numerical calculations are compared with measurements conducted at LMUs newly-built Laboratory for Extreme Photonics. A regenerative amplifer is set up to quantify the roundtrip gain at different pumping powers and wavelengths. The temperature of the pumped disk and its deformations as well as the single pass gain are measured, too. All measurements are in reasonable agreement with theory. After the motivation for this work some basic properties of lasers are introduced. In chapter 3 the basics of thermodynamics and its application to laser gain media, especially Yb:YAG, will be covered. The previous considerations will be numerically applied to the case of a thin-disk regenerative amplifer in the 4. chapter. Additional aspects, like its cavity and nonlinear effects, will be considered, too. Chap. 5 will give a description of the experimental methods and setups used to check the numerical predictions while the raw measured data and its interpratation are stated chap. 6 and 7

Canon Black Label Zero (FSC) ist ein einzigartiges, multifunktional einsetzbares Büropapier auf höchstem Niveau der Nachhaltigkeit. Es ist hochweiß, mit homogener Blattformation, und verfügt über hervorragende Laufeigenschaften. Seine Umweltverträglichkeit wird mehrfach dokumentiert und ist in der Summe einzigartig: Als Ausweis der Einhaltung ökologischer und sozialer Standards bei der Waldbewirtschaftung ist Canon Black Label Zero FSC zertifiziert. Bei der Zellstoffbleiche wird auf den Einsatz von Chlor und Chlorverbindungen völlig verzichtet (100 % chlorfrei gebleicht - TCF). Die Umweltzeichen EU-Blume und Nordischer Schwan belegen u.a. die Minimierung des Energieverbrauchs bei der Herstellung. Darüber hinaus ist Canon Black Label Zero Papier über die gesamte Produktkette – von der Holzernte bis zur Anlieferung bei unseren Kunden – zu 100 % klimaneutral. Canon Black Label Zero wird mit null CO2 Emissionen produziert (CO2-neutrale Herstellung). Die weitgehend reduzierten, jedoch unvermeidlichen Kohlendioxid-Emissionen, die vor allem im Bereich der Transportlogistik anfallen, werden durch Investition in ein international anerkanntes Klimaschutzprojekt kompensiert.

Since 2008, the Global Center of Excellence (COE) at Kyoto University, Japan, has been engaged in a program called Energy Science in the Age of Global WarmingToward a CO2 Zero-Emission Energy System. Its aim is to establish an international education and research platform to foster educators, researchers, and policy makers who can develop technologies and propose policies for establishing a CO2 zero-emission society no longer dependent on fossil fuels. It is well known that the energy problem cannot simply be labeled a technological one, as it is also deeply involved with social and economic issues. The establishment of a low-carbon energy science as an interdisciplinary field integrating social sciences with natural sciences is necessary. The Global COE is setting out a zero-emission technology roadmap and is promoting socioeconomic studies of energy, studies of new technologies for renewable energies, and research for advanced nuclear energy. It has also established the Global COE Unit for Energy Science Education to support young researchers as they apply their skills and knowledge and a broad international perspective to respond to issues of energy and the environment in our societies. Comprising the proceedings of the Third International Symposium of the Global COE Program, this book follows on the earlier volumes Zero-Carbon Energy Kyoto 2009 and 2010, published in March 2010 and February 2011, respectively.

Catalysis to produce hydrogen

The share market of hydrogen is increasing with the implementation of fuel cell systems and the growing demand for zero-emission fuels. Hydrogen production by using metal catalyst will need to increase with this growing market. However, some carbon is deposited on the catalyst but there was a window of operation where the deposited carbon did not have too great an effect on hydrogen production under different conditions. Carbon formation deactivates the catalyst, resulting in short life cycles. In order to improve process performance, in particular minimizing catalyst deactivation caused by carbon formation and maximizing the yield of hydrogen product, the addition of the promoters to catalyst is the most familiar method. The book is focused on the art of the promoters application on metal catalyst for hydrogen production from the methane steam reforming process at high pressure and the steam iron process over promoted Fe-oxide based catalyst.
