    press release — Our knowledge of how electrons behave in atoms and molecules is steadily increasing. This is largely due to the advances in attosecond physics that have taken place over the past two decades. Professor Ferenc Krausz was one of the pioneers in this young field. Indeed, he was the first to break into the attosecond domain, generating pulses of light with sub-femtosecond durations in 2001. Such ultrashort flashes can be used to study the ultrafast dynamics of electrons within atoms. Krausz has now published a book that traces the development of attosecond physics. Entitled “Electrons in Motion”, it draws on all the knowledge, experience and insights he has acquired in the field. Readers will find here a compact and chronologically ordered collection of his most important scientific publications, which have appeared in the world’s leading journals, such as Science and Nature, in the last 20 years. Each of the book’s 12 chapters focuses on a notable milestone in the evolution of attosecond physics. Krausz not only describes the background to these breakthroughs in introductory commentaries, he also provides colorful and informative illustrations, and intriguing impressions of life and work in the Laboratory for Attosecond Physics, which is jointly run by the Max Planck Institute for Quantum Optics and the Ludwig-Maximilian University in Munich. The volume ends with a fascinating look at how the developments in laser technology that have made attosecond physics possible could be leveraged for practical purposes in the not-so-distant future. Among the applications now under exploration is the use of laser-based molecular spectroscopy for the early diagnosis of life-threatening diseases.

    Expert for Blood Samples

    short report — At the beginning of October Dr. Frank Fleischmann joined the Broadband Infrared Diagnostics (BIRD) team led by Dr. Mihaela Zigman. Fleischmann began his career in biology as a botanist, but later switched to medical research. Before taking up his present position as a member of the BIRD team, he worked for a commercial provider of genetic tests, including the genotyping of cancer patients, for example. Fleischmann’s role in the BIRD team is akin to that of an archivist. He is responsible for the cataloging and storage of blood samples. Needless to say, accurate documentation and painstaking handling of test samples are of fundamental importance in medical research. After all, its ultimate goal is to produce a therapeutic agent or procedure that will be used to treat real patients every day. Fleischmann is also in charge of the database specially developed for the Lasers4Life project, and meticulously documents everything done with each and every one of the vital samples in his care.At the moment, the samples of blood plasma and the sera obtained from them are being stored at a temperature of −80°C. However, even this temperature is not low enough for long-term storage of such samples, as slow ice recrystallization alters their consistency, and after a certain time they have to be discarded. Fleischmann is working on an automated cooling system based on liquid nitrogen as the refrigerant, which will allow the samples to be kept at temperatures as low as −180°C. This is sufficiently cold to inhibit ice recrystallization in the liquid – and under these conditions, the constituents of the various blood fractions will remain unchanged for decades. Thus, as even more advanced methods of laser spectroscopy are developed in the future, the new system will enable the BIRD team to re-examine the samples already collected.

    press release — Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of health. Researchers at the Laboratory for Attosecond Physics (LAP) – a joint venture between Ludwig-Maximilians-Universität (LMU) and the Max Planck Institute of Quantum Optics (MPQ) in Garching near Munich – want to use brilliant infrared light to study molecular disease markers in much greater detail, for example to facilitate early stage cancer diagnosis. The team has developed a powerful femtosecond light source which emits at wavelengths between 1.6 and 10.2 micrometers. This instrument should make it possible to detect organic molecules present in extremely low concentrations in blood or aspirated air.

  • April 17, 2018

    press release — Researchers from Ludwig-Maximilians-Universität (LMU), the Max Planck Institute of Quantum Optics (MPQ) and the Technical University of Munich (TUM) have taken a major step towards the clinical application of a new laser-based source of X-rays. They recently demonstrated that the instrument enables the tomographic reconstruction of the three-dimensional fine structure of a bone sample within a few minutes. Up to now, laser-based measurements of this sort took several hours. The breakthrough was made possible by the further development of ATLAS, the high-performance laser in LMU’s Laboratory for Extreme Photonics (LEX Photonics) der LMU on the Research Campus in Garching. Reconstruction of the sample from the imaging data was also facilitated by the use of specially designed computer programmes.

    press release — Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort light pulses in the infrared and visible regions of the spectrum. Extremely high-energy laser pulses, each lasting for a few femtoseconds, have made spectacular experiments possible, which have in turn yielded revolutionary insights. Above all, the growth in understanding of the interaction between light and electrons opens up entirely new prospects for the future of electronics. In the journal Review of Modern Physics (10 April 2018), Dr. Stanislav Kruchinin, Prof. Ferenc Krausz and Dr. Vladislav Yakovlev from the Laboratory for Attosecond Physics (which is jointly run by Ludwig-Maximilians-Universität (LMU) and the Max Planck Institute of Quantum Optics (MPQ)) in Munich, provide a timely overview of current research in ultrafast solid-state physics. They describe recent breakthroughs and take a look at what we can expect from the field in the coming years.

    press release — Infrared light has a keen sense for molecules. With the help of this light, researchers are able to go in search of the small particles which shape and determine our lives. The phenomenon, in which infrared light sets molecules in vibration, is pivotal in this search. Scientists are exploiting this phenomenon by using infrared light to analyze the molecular makeup of samples. In the hope that this analysis can become even more exact, the laser physicists from the Laboratory of Attosecond Physics (LAP) at the Ludwig-MaximiliansUniversität(LMU) Munich and the Max Planck Institute of Quantum Optics (MPQ) have developed an infrared light source that has an enormously broad spectrum of wavelengths. This light source is the first of its kind worldwide and can be used to help detect the smallest amounts of molecules in liquids like blood.

    Awarded multilayer coatings design

    short report — Dr. Michael Trubetskov won four First Prizes in Design Contest Awards (Optical Interference Coatings Topical Meeting 2016) of the Optical Society of America (OSA). The first design problem of this year involved a dispersive mirror with maximum negative GDD (sub-problem A1) and with specified GDD level (sub-problem A2). In both cases the allowed GDD oscillation level was limited to 10%. The second problem was related to the design of a reflector with complicated spectral reflectance (sub-problem B1). In sub-problem B2 it was necessary to take into account complicated multilayer deposition conditions and to optimize overall performance. The contest takes place every three years, in order to better understand the possibilities and limitations of the current state-of-the-art theory/software for optical interference coatings. In this contest 18 participants from Germany, USA, France, Japan, China took place. The results of the Design Contest will be published in the featured issue of Applied Optics devoted to OIC 2016.

    press release — The interaction between light and matter is of key importance in nature, the most prominent example being photosynthesis. Light-matter interactions have also been used extensively in technology, and will continue to be important in electronics of the future. A technology that could transfer and save data encoded on light waves would be 100.000-times faster than current systems. A light-matter interaction which could pave the way to such light-driven electronics has been investigated by scientists from the Laboratory for Attosecond Physics (LAP) at the Ludwig-Maximilians-Universität (LMU) and the Max Planck Institute of Quantum Optics (MPQ), in collaboration with colleagues from the Chair for Laser Physics at the Friedrich-Alexander-Universität Erlangen-Nürnberg. The researchers sent intense laser pulses onto a tiny nanowire made of gold. The ultrashort laser pulses excited vibrations of the freely moving electrons in the metal. This resulted in electromagnetic ‘near-fields’ at the surface of the wire. The near-fields oscillated with a shift of a few hundred attoseconds with respect to the exciting laser field (one attosecond is a billionth of a billionth of a second). This shift was measured using attosecond light pulses which the scientists subsequently sent onto the nanowire.

  • May 23, 2016

    press release — Light waves might be able to drive future transistors. The electromagnetic waves of light oscillate approximately one million times in a billionth of a second, hence with petahertz frequencies. In principle also future electronics could reach this speed and become 100.000 times faster than current digital electronics. This requires a better understanding of the sub- atomic electron motion induced by the ultrafast electric field of light. Now a team of the Laboratory for Attosecond Physics (LAP) at the Max-Planck Institute of Quantum Optics (MPQ) and the Ludwig-Maximilians-Universität (LMU) and theorists from the University of Tsukuba combined novel experimental and theoretical techniques which provide direct access to this motion for the first time.

  • February 4, 2016

    press release — In the race to establish ever-faster electronics, light could play an important role. For instance, using light pulses of a precisely controlled waveform, physicists aim to switch electric currents in electronics circuits with light frequencies. But will electrons in such circuits follow light oscillations instantaneously? How fast will electrons react to the push of a “light-based” button? Or, from a more fundamental perspective: how fast do electrons bound in atoms, molecules or solids respond to light? Now, an international collaboration of physicists led by Dr. Eleftherios Goulielmakis, head of the research group “Attoelectronics” at the Max Planck Institute of Quantum Optics, researchers from Texas A&M University, USA, and the Lomonosov Moscow State University, " have been able to track the effect of this delay for the first time". By creating the first optical attosecond pulse and using it to set electrons in krypton atoms in motion, they discovered that it takes as long as 100 attoseconds for electrons to respond to the electromagnetic forces of light.

  • January 19, 2016

    press release — Those who want to explore the microcosm need exact control over laser light. Only with its help is it possible to explore electron motion and to influence their behavior. Now, scientists at the Laboratory for Attosecond Physics at the Max Planck Institute of Quantum Optics (MPQ) and the Ludwig-Maximilians-Universität Munich (LMU) have developed a measuring system that is able to determine laser pulses with a wide bandwidth in the infrared spectrum of light precisely. In the infrared wavelength range as short as 1200 nanometers this was only possible with the help of complex vacuum systems until now. The new system can be used for the precise generation of attosecond-duration light bursts for the exploration of atomic systems, as well as for the controlled dynamics of electrons in crystals.

  • September 21, 2015

    press release — Scientists often need to detect and measure levels of specific substances in a sea of irrelevant molecules, and infrared light offers an ideal tool for this task. Infrared radiation is invisible to the human eye, but molecules react with mid-infrared light in ways that are extremely sensitive to their precise atomic structure. This provides a means of identifying with great specificity molecular solutes present in very low concentrations. Lasers that generate light in the mid-infrared range suitable for use in molecular sensors are therefore the subject of intensive research. Now teams from the Ludwig-Maximilians-Universität (LMU) and the Laboratory for Attosecond Physics at the Max Planck Institute of Quantum Optics (MPQ), in collaboration with the Institute of Photonic Sciences (ICFO) in Barcelona, have developed a unique source of coherent radiation for this purpose.

    press release — The interaction of high-intensity laser light with solid targets could someday serve as the basis of table-top sources of high-energy ions for medical applications. An international team led by physicists of the LMU affiliated with the Munich-Centre for Advanced Photonics (MAP), a Cluster of Excellence based in Munich, and in cooperation with scientists from the Max Planck Institute of Quantum Optics, has taken another step towards this goal. They have done so by boosting the efficiency of a technique that uses extremely intense pulses of laser light to eject packets of high-energy ions from diamond-like carbon foils. In their experiment, the researchers coated one side of the foil with carbon nanotubes. Upon laser irradiation, the layer acts like a lens to focus and concentrate the light energy on the foil, which results in the production of much more energetic ion beams. This makes experiments with high-energy carbon ions on cells feasible for the first time, and brings light-driven generation of ionizing radiation closer to practical application.
