 || '''13.01.2017''' || '''Philipp Dietrich (KIT)''' || '''Printed Micro-Optics and More[[BR]][[BR]]'''3D-micro-printing based on two-photon-absorption allows to manufacture free-form-structures of an arbitrary shape. The particular of this method is the creation of the desired structure at the very location of its later application. A subsequent positioning is not required, i.e. a perfect alignment is possible. [[BR]][[BR]]Only in this way, 200nm silicon waveguides can be linked via 3d-printed free-form-waveguides („photonic-wirebonds“), which solves fundamental problems of integrated optics. Other options result from the capability to print free-form-lenses onto facets of optical components -like optical fibers-, whereby light is coupled much more efficiently into such fibers. But applications are not restricted to optics alone: Even the needle of a scanning-force-microscope is printable, such that each probe gets its optimal scanning head. [[BR]][[BR]]Philipp Dietrich's talk will focus on optical devices, but will also highlight possible applications for astronomy.[[BR]][[BR]]Presentation: German                  [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2017S1/2017-01-13_PrintedMicroOptics.pdf Slides: English][[BR]]Questions: German, English ||

[[BR]][[BR]]The main experimental results will be presented and compared with the requirements. In addition, a report on the activities in the area of the LGS systems R&D will be given. These are being done in collaboration with the AO community in the ESO member           states, where currently two of in total four tasks have been completed.[[BR]][[BR]]Domenico Bonaccini Calia will           also report on the systematic measurement of the LGS return fluxes and on the LGS-AO loop results obtained with largely elongated LGS, similar to those foreseen for the EELT configuration. An outlook on the future, approved R&D will also be given.[[BR]][[BR]]Presentation: English[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2017S1/2017-02-03_ESOLGS.pdf Slides: English][[BR]]Questions: German, English ||
