Sven Teichmann''s doctorate features experimental work on a high-harmonic generation source and coherent diffractive imaging. High-harmonic generation allows generating coherent and laser-like extreme- ultraviolet and soft x-ray radiation based on the frequency-upconversion of laser light. A novel and successful approach of employing harmonic emission that consists of multiple harmonic orders is presented. This emission is utilized for coherent diffractive imaging by illuminating a sample of unknown structure, e.g. a membrane protein. The diffractive image of that sample is then processed by means of computational algorithms and the structure of the sample can be recovered. This innovative work of a very high level of technical achievement is considered as internationally significant by world leaders in the field of high- harmonic generation and may prove valuable particularly for time-resolved spectroscopy, sources of soft x-ray and extreme-ultraviolet radiation, and imaging based on harmonic emission.

Sven Teichmann was born in Germany in 1978. He studied Physics at the Technische Universität München and specialised in Quantum Optics at the Max-Planck-Institut für Quantenoptik. His doctorate was performed in Melbourne at the ARC Centre of Excellence for Coherent X-Ray Science. Sven graduated as Doctor of Philosophy / Ph.D. Science in 2009.
