innoFSPEC and astrOOptics seminar

innoFSPEC and astrOOptics public status seminar, 14 Nov, Potsdam

On 14th of November 2017, we give our next public status seminar hosted as a joint seminar by the innovation centers innoFSPEC Potsdam and ultra optics Jena (joint project astrOOptics). In the seminar, we plan to show the results of recent activities and research projects as well as prospects for 2018. During the subsequent poster session and lunch break, we are looking forward to discussing topics further with our guests.

The event will take place from 10 am to 1 pm at the Leibniz-Institute for Astrophysics Potsdam (AIP), An der Sternwarte 16, 14482 Potsdam.

Abstract:

The coherent laser light in different spectral regions is needed for the applications in Science, Medicine and Technology. The standard laser sources normally have a special wavelength or a very limited tunablity. Nonlinear Optics has provided a solution for these problems via various nonlinear interaction schemes. By appropriate application of different second and third order nonlinear interactions, it is possible to cover a wide area across the whole spectral range from Vacuum UV to Mid-infrared. Because of the very small values of the nonlinear interaction coefficients (10E-12 and 10E-24 for second and third order nonlinearities, respectively) higher intensities of ultrashort pulses give them the priority for the efficient interactions. In this talk we will try to present the results of the successful application of different nonlinear interactions using femtosecond pulses for the efficient generation of tunable ultrashort pulses across the different parts of the spectrum.

About the lecturer:

Dr. Masood Ghotbi received his Ph.D. degree in Physics in 2005 at ICFO-Institute of Photonic Sciences (Barcelona, Spain) with a thesis focused on the theoretical and experimental investigation on frequency conversion of femtosecond pulses with BIBO nonlinear crystal. He developed later optical parametric sources at ICFO and Max Born Institute, Berlin. Since 2012 is working as the head of Physics department at the University of Kurdistan in Iran.

Exchange of experiences with IAC-TEC

Exchange of experiences with IAC-TEC, La Laguna Tenerife Oct 30 - Nov 3, 2017

Upon invitation of the Instituto Astrofisica de Canarias (IAC) in La Laguna, Tenerife, Martin Roth visited IAC to give two seminars on the subjects of innoFSPEC science and transfer of knowledge and technology / innovation management. Intense discussions with IAC's newly founded innovation centre IAC-TEC revealed various similarities with innoFSPEC Potsdam. Both parties agreed to continue the exchange of experiences with the goal of future collaborations, in particular with a focus on innovation in astronomical instrumentation and medical diagnostics.

innoFSPEC fellows visiting the Chinese Academy of Sciences, Beijing

Dr.-Ing. Anne Hartwig to present on innoFSPEC core technologies at the State Key Laboratory on Multiphase Complex Systems, Institute of Process Engineering (http://eng.mpcs.cn/), Chinese Academy of Sciences, Beijing, China. Dr. Hartwig gave a talk on "Photon Density Wave Spectroscopy as a new approach for monitoring the cooling cristallization from highly concentrated solutions".

The sponsorship of the German DAAD is gratefully acknowledged, allowing for in-depth discussions on how to link the German optical fiber instrumentation activities at innoFSPEC with the analytical challenges of Prof. Yongsheng Han's Chinese research team.

SALSA fellow Christian Heck @ Falling Walls Lab 2017, Berlin

How can diseases be detected as early as possible by analyzing human blood? This is the topic of Christian Heck, doctoral fellow at the School of Analytical Sciences Adlershof (SALSA) in Adlershof. His project has only been made possible by the close cooperation of three research institutions in Berlin-Brandenburg: University of Potsdam (Jprof Dr. Ilko Bald, innoFSPEC research group leader), Bundesanstalt für Materialforschung und -prüfung (BAM) and the Humboldt-University Berlin (Prof. Dr. Janina Kneipp).

With his 3 minutes pitch "Breaking the Wall of Biomarker Sensing" Christian Heck has recently won the Falling Walls Lab in Adlershof. He will now represent Adlershof in the Berlin finals at the Falling Walls Lab, 8/9 November 2017.

Congratulations, Christian, to this great success!
