The requirements for deformable mirrors and for closed-loop control systems of these mirrors are analyzed. Several deformable mirrors have been characterized and the results are presented. Currently available membrane mirrors deform under laser load and need further development before they can be used for aberration correction of solid state lasers above some tens of Watts. Nevertheless, the results are encouraging and the requirements are within reach of currently available technology. Finally, we demonstrate an Nd.YVO4-laser with a closed-loop adaptive resonator and more than 6 W of output power. The closed-loop system was able to compensate artificially introduced aberrations from a phase plate.}, language = {de} } @article{HeuckNeumayerKuehletal.2006, author = {Heuck, Hans-Martin and Neumayer, Paul and K{\"u}hl, Thomas and Wittrock, Ulrich}, title = {Chromatic aberration in petawatt-class lasers}, series = {Appl.

Usually, chromatic aberration associated with these optical elements is neglected. By means of numerical simulations, we show how the chromatic aberration affects the focal intensity pattern. In particular, we make quantitative predictions of how chromatic aberration decreases the focused peak intensity. Furthermore, we prove the feasibility of a new interferometer that measures the temporal pulse front distortions which arise from expansion telescopes. We also propose a scheme that pre-compensates these distortions.}, language = {en} } @incollection{LiuHoelscher2006, author = {Liu, L. and H{\"o}lscher, U.}, title = {Evaluation of graphical Symbols used in Intensive Care Units (ICU): Comprehension among Users in Different Countries; European Society for Computing and Technology in Anesthesia and Intensive Care}, year = {2006}, language = {en} } @article{ValenciaGauppGudatetal.2006, author = {Valencia, S. and Gaupp, A. and Gudat, W. and Mertins, H.-Ch. and Oppeneer, P.
