Acknowledgements
It is with pleasure that I list some of the persons by name who have been involved in this work by being
helpful and inspiring.
First of all, I sincerely thank Heinz Helmers for five years of enjoyable and fruitful collaboration, and also
for his thorough review of the first version of this thesis that has definitely contributed to making it more
readable and consistent.
Also, I am indebted to Klaus Hinsch for valuable comments, and for a considerable freedom to organise
and develop my research activities in a way that enabled keeping up a productive atmosphere and good
humour all the time.
I am grateful to Volker Mellert for his benevolent readiness to take over the part of the second referee.
Then I would like to mention Christian Kunze and Volker Wilkens for the joint research of our largespeckle
measurements, which was an enriching and memorable experience.
The same is true of the research project about pure in-plane SPS that R. S. Sirohi and I performed together
when he was with our workgroup; in fact he taught while we were working, and I am grateful for what I
learnt from him.
Alexander Brozeit, Henning Sagehorn and Roman Schuh contributed the phase stabilisation unit and a
good deal of teamwork, which enabled bringing our expertises together successfully.
I thank my office colleague, Thomas Fricke-Begemann, for many interesting discussions, in particular the
exciting excursions through the frequency plane, occasional co-operation, and his large contribution to the
pleasant working atmosphere.
Also the other members of the Applied Optics workgroup at Oldenburg are a great staff to work with, and
I appreciate the collegial and easy ambience in which this work was done, as well as their interest,
comments, their help and asking for help.
The exchange of ideas with colleagues from other laboratories, and their pleasant and inspiring company
at conferences, have contributed to the progress of the work and always added an extra push of
community feeling and motivation.
I am deeply grateful to my parents who have provided every kind of support and encouragement one can
wish, which I feel was an essential basis to cope with the strains associated with such a project.
Another big thankyou goes to Tatjana, for her patience with my always being busy, for all her successes in
keeping me from working on week-ends, and for the constant sunshine of her love.
Finally, thank you, dear reader, for your interest.
