    Field-resolved infrared spectroscopy of biological systems
    press release — In cooperation between the Laboratory of Attosecond Physics at the Max Planck Institute of Quantum Optics and the Centre for Advanced Laser Applications of the Ludwig-Maximilians-Universität München, the King Saud University Riad and the Center for Molecular Fingerprinting (Budapest, Hungary), we have developed a molecular spectroscopy technique that overcomes long-standing limitations of traditional techniques, like Fourier-transform infrared spectroscopy. A powerful femtosecond laser delivers 28 million pulses per second, with highly repeatable waveforms, comprising merely a few infrared-electric-field oscillations. …

    One of the most cited researchers
    short report — According to Web of Science, Prof. Ferenc Krausz is one of the most cited researchers worldwide. The Web of Science is the information and technology provider for the global scientific research community. Each year, Web of Science identifies the world’s most influential researchers. The selection marks the few who have been most frequently cited by their peers over the last decade. In 2020, fewer than 6,200, or about 0.1%, of the world's researchers, in 21 research fields and across multiple fields, have earned this exclusive distinction.

    Generation of mid-infrared using a BGSe nonlinear crystal
    press release — The „field resolved infrared science“ group has demonstrated for the first time the generation of octave-spanning mid-infrared using a BGSe nonlinear crystal. A Cr:ZnS laser system delivering 28-fs pulses at a central wavelength of 2.4 µm is used as the pump source, which drives the intra-pulse difference frequency generation inside the crystal. As a result, a coherent broadband mid-infrared continuum spanning from 6 to 18 µm has been obtained. It shows that the BGSe crystal is a promising material for broadband, few-cycle mid-infrared generation via frequency down conversion with femtosecond pump sources. Original …

    "Lasers | Light | Life": the end of the road
    short report — It is with a modicum of melancholy, leavened with a pinch of justified pride, that we bid farewell to the exhibition on “Lasers | Light | Life” at the ESO Supernova, which has now closed. The exhibition in the Rotunda of the ESO Supernova Planetarium and Visitors’ Centre was designed to acquaint the general public with the history of the laser and with current trends in the continuing development of laser-based technologies. The show was a great success, attracting well over 50,000 people. – And the many positive comments recorded in our Digital Visitors’ Book were ample reward for the work we put into the exhibition. …

    The coming-of-age of femtosecond enhancement cavities
    press release — Ioachim Pupeza and Maximilian Högner from the Field-Resolved Infrared Metrology Research Group have co-authored the Review Article “Extreme-ultraviolet frequency combs for precision metrology and attosecond science” in Nature Photonics, surveying the coming-of-age of cavity-enhanced high-order harmonic generation for precision time- and frequency-domain metrology. Femtosecond modelocked lasers emitting trains of coherent visible/infrared pulses have steadily advanced our understanding of basic processes in nature. For example, optical clocks employ frequency-comb techniques for the most precise measurement of time, …

    taking it personally: a new blood-based test for monitoring persons’ health
    press release — A new study carried out by a team of laser physicists, molecular biologists and physicians based at LMU Munich and the Max Planck Institute for Quantum Optics has confirmed the temporal stability of the molecular composition of blood in a population of healthy individuals. The data provide a basis for a new method of monitoring the constituents of blood and detecting alterations that reveal changes in a person’s state of health.
