Fritz Keilmann (*1942) studied meteorology, biophysics and physics in Munich. As a postdoc he worked from 1972 at MIT on precision spectroscopy and invented a record-strong gas laser tunable from microwave to infrared frequencies. This enabled him, from 1974 at the MPI for Solid State Physics (Stuttgart), to pioneer coherent phonon propagation and nonlinear infrared spectroscopy of dielectrics and semiconductors, even ultrafast dynamics. He advanced optics instrumentation with all-metal polarizers and filters which he commercialized (Lasnix) in 1984. His all-metal infrared focusing helped him understanding quantum-Hall physics and achieving, from 1995 at the MPI for Biochemistry (Martinsried), super-resolution near-field optical microscopy (s-SNOM) which he and R. Hillenbrand commercialized (Neaspec) in 2007. He pioneered both dual-frequency-comb spectroscopy and, from 2007 at the MPI of Quantum Optics (Garching), infrared supercontinuum sources for s-SNOM to perfect nano-FTIR chemical nanoscopy. In 2009 he was awarded the K.J. Button prize. Since retiring from Max-Planck (2012) and from Neaspec (2017) he continues at the LMU physics department pioneering (2021) nano-FTIR of cells living in their aqueous environment.

I am application engineer for the Neaspec team of attocube and long-time user of near-field microscopy. My background is solid state physics (RWTH Aachen University) and I was introduced to the s-SNOM technology already during my Master’s studies in the Nano-optics group of Prof. Thomas Taubner. During five years in San Sebastian, I have worked in the group of Prof. Rainer Hillenbrand at nanoGUNE with infrared near-field microscopy on a broad range of samples ranging from polymer, bio, semiconductor, 2D materials and others. As application engineer of attocube I am now involved in an even broader range of projects, spanning spectral ranges from visible to terahertz, experiments at cryogenic temperatures and more.

I was born in the far east of USSR in 1987. Then I grew up in Ukraine, with my mother being a math teacher, and my grandmother being a teacher in physics. No surprise I was good at these subjects, however, my deep interest in physics has begun later in a high school, thanks to my teacher Nikolay F. Babenko. I was quite good in solving challenging physical problems, therefore I participated (with a certain success) in All-Ukrainian Olympics in Physics. Then I entered Moscow Institute of Physics and Technology (State University), the best university for physicists in post-soviet area at that time. First, I went hard-core into theoretical physics direction, but later found it boring and hopeless, therefore I switched then into experimental physics. By a pure coincidence I was invited to Odense, Denmark, by prof. Sergey I. Bozhevolnyi (University of Southern Denmark), which was a completely new world for me. I liked this world and put all my efforts into staying here. One year later, my efforts were rewarded, and I got a PhD position in his group. Since then, I got stuck here, because I like living in Denmark as a whole and working environment in our group in particular. Currently I enjoy my life with my lovely wife Oksana, daughter A
