    advanced multilayer optics (AMO)
    We aim at pushing the frontiers of designing, fabricating and characterizing multilayer optics for sub-cycle control of infrared-to-ultraviolet laser light.
    Volodymyr Pervak — The optical multilayer structures have been driving the advancement of ultrafast laser technology towards ever broader bandwidth and ever shorter pulses. Deposition of dielectric layers with sub-nanometer accuracy permits manipulation of the spectral phase and amplitude of optical radiation over a full octave and beyond. With the help of design, fabrication, and characterization techniques defining the state of the art, We develop optical multilayers for wide-band light waveform synthesis all the way from the infrared to the ultraviolet.

    attosecond spectroscopy 2.0 (ATTO 2.0)
    Controlling and measuring ever faster electron dynamics with ever better accuracy is going to have applications across multiple disciplines.
    Nicholas Karpowicz and Vladislav Yakovlev — Attosecond science expanded our access to the microcosm. One exciting result is the possibility to craft a sub-femtosecond gate, allowing snapshots of the electromagnetic field faster than it can oscillate. We can directly record the waveform of light. Why is that exciting? When an electron moves, its motion is inscribed into the electromagnetic field – reading the waveform lets us reconstruct it. We can use this to observe processes that are too fast for traditional pump-probe spectroscopy.

    Within the vanguard of probing living systems, we develop electric field molecular fingerprinting for detecting human disease.
    Mihaela Žigman — As the molecular composition of living systems underlies their physiology, simultaneous probing of multi-molecular changes in complex organic media has the potential to phenotype any living system.

    field-resolved infrared spectroscopy (FRIS)
    We combine laser development with engineering to develop new instruments for future health monitoring with field-resolved infrared spectroscopy.
    Alexander Weigel — Field-resolved spectroscopy can capture the vibrational response of a molecular sample to excitation with a few-cycle mid-infrared pulse, directly in time domain, providing a sensitive fingerprint of the molecular composition and structure of the sample. We develop new waveform-stable few- to single-cycle infrared laser sources, together with high-dynamic-range field-resolved infrared metrology. Our instruments are the basis for future health monitoring based on infrared molecular fingerprinting, developed in close collaboration with the Center for Molecular Fingerprinting
