Since its invention it has triggered numerous applications in very demanding areas of science like e.g. ultra high resolution spectroscopy, calibration of (astronomical) spectrometers, precision ranging, optical clocks, ultra-pure micro-wave generation, frequency and time transfer. In a general sense it has become the swiss knife of precision metrology of time, frequency, and length. Even mass and gravitation have been reported to be measurable at increased precision using the frequency comb. [[BR]][[BR]]In the present talk Matthias Lezius will present todays technologies how to build optical frequency combs based on femtosecond lasers, and how to apply this device to various metrological challenges.

But also in other industrial fields, where products are driven by a low mass in conjunction with a high stiffness, like e.g. in vehicle construction or even sports equipment development, CFRP becomes more and more important.[[BR]][[BR]]There is an increasing trend to apply carbon fiber parts also in astronomical instrumentation. One of the pioneers in this field is the interferometric camera LINC-NIRVANA for the Large Binocular Telescope (LBT). The talk will also discuss other examples in other projects. In addition the properties and the manufacturing process of this interesting material will be described.[[BR]][[BR]]Talk: German[[BR]]Slides: English[[BR]]Questions: German, English || 34 34 || 27.02.2015 || Sascha Douffet || Occupational safety at MPIA || 35 35 || 06.03.2015 || Uwe Graser || MATISSE ||
