Dr. Peter Baum

teaser_baumPeter Baum and his team work on visualizing the ultrafast motion of atoms and charge densities by using electron diffraction. They are developing concepts, the successful implementation of which may push the frontiers of time-resolved electron diffraction into the few-femtosecond to sub-femtosecond regime.

Prof. Dr. Stefan Karsch

teaser_karschStefan Karsch, Zsuzsanna Major and their team develop the next generation of few-cycle laser sources with multi-terawatt peak powers at kHz and petawatt-scale powers at few-Hz repetition rates , which affords promise for the generation of attosecond kiloelectronvolt X-ray pulses for time-resolved X-ray diffraction with attosecond-picometre resolution.

Prof. Dr. Matthias Kling

teaser_klingMatthias Kling and his team pursue the development of a MHz-rate attosecond XUV source. They aim at reaching isolated attosecond pulses at high repetition rate, which can be utilized in nano-photonic and nano-plasmonic applications.

Dr. Vladimir Pervak

teaser_pervakVladimir Pervak and his team work on dispersive mirrors development. Specially developed optics components (mirrors, beam splitters, spectral filters, polarizers, chirped mirrors, dispersive mirrors) serve as key components in ultrafast laser experiments for few-cycle femtosecond laser pulses. Researchers are targeting to expand bandwidth, enhance damage threshold, reduce losses and increase dispersion in future.

Dr. Oleg Pronin

teaser_proninNext-generation oscillator technology relies on Yb doped thin-disk technology as one of its main building blocks. A unique combination of high average power, high repetition rate and high peak power is now possible, thanks to this technology. In contrast to laser amplifiers, we explore the power limitations of oscillators which generate femtosecond pulses directly and thus represent the simplest laser systems from this point of view. The sources are highly attractive as driving sources for the generation of the deep ultraviolet (VUV/XUV) and middle infrared (MIR) parts of the optical spectrum.

Dr. Ioachim Pupeza

teaser_pupezaOur research primarily addresses the development of novel tools and techniques for field-resolved spectroscopy (FRS) of molecular vibrations in the IR spectral region. With FRS we record the electric fields emitted by impulsively excited molecules as the most fundamental ensemble-averaged physical measurable of coherently oscillating microscopic molecular electric dipoles. The technologies and expertise developed in our group also impact on other fields, such as time-resolved photoelectron emission microscopy (PEEM) employing attosecond XUV pulses.

Dr. Mihaela Žigman

teaser_zigmanMihaela Zigman and her team work at the crossroads of laser physics and molecular medicine to explore molecular spectroscopic fingerprinting. Based on a powerful broadband femtosecond infrared laser source together with time-domain metrology, the objective is to employ quantitative molecular spectroscopy to detection of human health states.
