CFEL Chapter’s Visit to Karlsruhe

From May 5th to 9th, under the invitation of OSKar, 8 representatives of the OSA student chapter in Center for Free-Electron Laser Science (CFEL), Hamburg, paid a visit to Karlsruhe. We OSkar members organized lab tours for the guests in the Institute of Photonics and Quantum Electronics (IPQ), and Institut für Angewandte Physik (APH), KIT. In these labs, our KIT PhD students and post doctor gave detailed introductions of their work on fields of optical frequency comb, photonic wire, super resolution microscopy and fluorescence correlation spectroscopy.



After the lab tour, OSKar board guided our guests to Baden-baden, a small but beautiful city in south to Karlsruhe. There we enjoyed the typical scenery in the south-western Germany in late Spring. In the evening, there was a gathering of CFEL chapter’s and OSKar members in Stövchen. Our guests from Hamburg also enjoyed the classic southern food – Flammkuchen. Finally, the Hamburg OSAers invited our OSKar to visit the northern harbor city.



We (OSKar) are open and looking forward to interaction with other chapters. Although this time, it is the first cooperation between CFEL OSA chapter and OSKar, the events, including both academic communication and entertainment activities, really built up a bridge of friendship between the two chapters in the northern and southern Germany.


Fraunhofer Talk by Dr. Eilenberger, KIT 2016

On April 20th, OSKar invited Dr. Falk Eilenberger, from Fraunhofer IOF, to give a talk on applications on nano-optics. The talk was held in the lecture hall of Lichttechnisches Insititut (LIT), at the KIT. Our secretary, Orlando Torres introduced the speaker. This lecture gave rise to huge interest among the students. The most impressive part was the anticipation of the development of the future of optics, i.e. optics in a very small size down to the nano-scale.

Dr. Eilenberger’s talk gave our students a space for discussion about nanoscience. Nanoscience is not only the concern of optics, but also the focus of many other research directions. We can imagine that in the coming years, the applications in nano-optics and other branches of nanoscience will play a broader and more significant role in our life.


After the talk, our colleague in charge of public relations, Isabel Allegro, also interviewed some of the audience for feedback. The interviewees regarded this lecture as comprehensive and helpful. Our chapter will provide as more attractive activities as possible in the future.

Excursion to SICK AG, Waldkirch 2016

On January 27th, under the leading of Dr. Martin Lauer from the Institute of Measurement and Control Systems (MRT) at the KIT, a group of our OSKar members with other KSOP master students paid a visit to SICK AG. This company is located in Freiburg in Breisgau and has earned a reputation around Germany for its optical sensing technology.


The staff there guided us through their production line and logistics department, and gave us an introduction on the history and newly developed products of the company. Afterwards they made two presentations for us: one of them focused on the technical development of SICK’s products, and the other concerning mainly the career and job opportunities in the company. Through this visit, our students gained more knowledge on the optical sensing and its applications in security, communication and other fields.


Lasertag, Karlsruhe 2015

As part of the end-of-the-year traditions in OSKar, the Laser Tag 2015 Edition took place in Laser Base, located in the Oststadt (East City) of Karlsruhe on December 17th 2015.

DSC_0037While the first group was assembled, some OSKar members enjoyed the laser-themed pinball tables and a few drinks before listening to the instructions given by the Laser Base staff on the basic operation and rules for the game. A few OSKarians discussed the operation of the laser taggers and other more technical aspects of the game design while waiting for the next round.


Some of the veterans, such as our former president Patrik Rath and former Treasurer Phillip Brenner, rose through the scoreboard with ease. Nevertheless, many new OSKar members developed a quick feel of the game and wound up in the top 3 contenders for the scoreboard, making it difficult for the veterans to maintain the leadership of the board through the intense four rounds of 20-minute playthroughs.

DSC_0062Inside the arena, many members developed quick strategies to rise up on the scoreboard, while being observed with the infrared cameras located in the bases of each team and in the pit between the bases. The randomized team formations allowed for new strategies to be developed with new members of the group and developing good strategic planning to increase the points of each team.

After two hours of intense loading, reloading and tagging, the infamous group picture was taken as a memory of the good times and sharing the best moments of each playthrough.

DSC_0063Who will be the top rank-player next time? Stay tuned until next time!

A special thanks to our former board member Aso Rehîmzadegan for putting together this stunning event!

Stammtisch, Karlsruhe Christmas-market 2015

DSC_0058Last week, OSKar organized the traditional Stammtisch at the Karlsruhe Christmas-market. OSKarians and friends got together to enjoy the Christmas spirit and the typical food and drinks of this time. We also organized a small “treasure hunt” in order for everyone to get to know the different stands of the Christmas-market.


Winners of the treasure hunt, Artyom and Tatyana
