However, many applications are demanding higher average powers from these ultrashort pulse sources. This can be achieved by combining direct diode pumping with novel gain media designs. In particular, ultrashort pulse fiber lasers are now delivering average powers in the kW range. However, the design of fiber lasers, producing pulses with high peak-powers, is challenging due to the impact of nonlinear effects. To significantly reduce these detrimental effects in ultrashort pulse fiber amplifers, the combination of chirped pulse amplification (CPA) and large mode area fibers is employed. Using these methods, the pulse energy of fiber lasers has been steadily increasing for the past few years.

### Title: ['Fast STED microscopy']
### Abstract:
['The spatial resolution of optical far-field microscopes was hampered by diffraction until STED microscopy broke the diffraction limit. This thesis for the first time combines the high spatial resolution of STED microscopy with high temporal resolution to Fast STED microscopy. It heralds the study of fast dynamic processes via STED microscopy: diffraction unlimited movies with 200 images per second are recorded from colloids; video-rate imaging is achieved in living cells. In particular, the diffusion of 36 nm particles is shown at 80 frames per second (fps); the processes at the growth front of a colloidal crystal of particles as small as 200 nm are visualized at 200 fps.

### Title: ['Lebenssinn in schweren Erkrankungen älterer Menschen : eine empirische Untersuchung über Selbsttranszendenz Sinnerfüllung Sinnkrise im Alter']
### Abstract:
[['The empirical research based on 36 seriously ill and elderly people is exploring the question, which possibilities are to be meaningful and give sense to the own exitence. The main evidence is a vertical transcendence to a very big degree. An important result of research is the so called paradox of fulfilling life. The study has shown a high level of fulfilling life through lifetime on one hand; on the other hand a high degree of crisis of meaning for the elderly, seriously ill people has been the result of this study. The absence of prospect, the "fact of falling into disuse" and the ongoing fragility cause these consequences. Accepting the limits of designs for life an possibilities of acting, as well as the integration into a coherent conception of life could be supported by forms of horizontal and vertical self trancendence.', 'Die empirische Untersuchung an 36 schwer erkrankten älteren Menschen geht der Frage nach, in welchen Bereichen sich Sinnerfüllungsmöglichkeiten bieten. Dabei zeigte sich ein hohes Ausmaß an vertikaler Selbsttranszendenz. Ein wichtiges Untersuchungsergebnis ist das "Sinnerfüllungsparadoxon". Die Untersuchung hat auf der einen Seite eine hohe Sinnerfüllung über die gesamte Lebensspanne aufgewiesen, auf der anderen Seite aber auch gezeigt, dass der ältere, schwer erkrankte Mensch an einer schweren Sinnkrise leidet. Perspektivlosigkeit und das "Faktum", nicht mehr gebraucht zu werden, sind neben der fortschreitenden Gebrechlichkeit als Ursachen dafür auszumachen. Das Akzeptieren der Grenzen der eigenen Gestaltungs- und Handlungsfähigkeit und die Integration in einen stimmigen Lebensentwurf könnten durch eine horizontale und vertikale Selbsttranszendenz ihre Unterstützung finden.']]

It was rather fortunate that the pupils\' files did not only contain the letters written by parents but in most cases also carbon copies of the replies by the school heads. The central theme of a short first paragraph is the parents\' reaction to the "Gestalt" of the school, i.e. its geographical situation, its setting in a rural landscape and the outer and inner appearance of the twelve buildings which the school complex comprised at the time. The main part of this dissertation focuses on the circumstances that affected the way in which the school community lived and worked, as those conditions made the idea of a new pedagogical concept come true, thus providing the background to an analytical appraisal by the parents related with the school. Therefore a connection is established between two spheres: 1} Paul Geheeb\'s perspective on the following issues: - What was his approach to the concept of "school"? - What was his type of school to be for the children and adolescents entrusted to his care? - What model of learning and education did he follow? - What picture of humankind served him as guideline? - How did he translate his ideas into action? and 2)the parents\' attitude expressed in the answers to the following questions: - What in particular made parents send their children to this independent school? - What was their understanding of education and learning based on? - How did mothers and fathers judge the pedagogic scheme pursued by the school their children attended? - Why did some parents actively support the Odenwaldschule and cooperate with the Geheebs while others turned passionate opponents of the couple and their educational policies? The last chapter provides insight into the relations between the parents and the Odenwaldschule at the time of political turmoil.
