His paper “Femtosecond Written Chirped Fiber Bragg Gratings for Dispersion Control at 2 μm” received the BGPP Best Student Award. In his lecture, the researcher presented Chirped Fiber Bragg Gratings (CFBG), which can be used for dispersion control (i.e. different propagation of different wavelengths in an optical system). These CFBGs are used in short-pulse fiber laser systems in chirped pulse amplification (CPA). CFBGs with a central wavelength of 1910 nm were presented for this purpose, in which the dispersion properties could be specially adapted. The use of femtosecond lasers to generate the CFBG enables the efficient realization of gratings in fibers for the 2 µm wavelength range with reflectivities of over 70%.
Georg Schwartz is delighted: “I am very proud to have received the BGPP Best Student Award. It not only recognizes my own work, but also that of my colleagues in Prof. Nolte's working group, whom I thank for their fruitful support and productive collaboration. The award confirms that the topic of CFBGs as components for ultrashort pulse laser systems, in this case CPA systems, is currently in demand and very interesting.”
