    Prof. Nasser M. Al-Daghri visits Garching

    short report — Together with Prof. Abdallah Azzeer, Prof. Nasser M. Al-Daghri from King-Saud-University has complied with an invitation of Prof. F. Krausz to pay a visit to his MPQ-LMU laboratories and present a colloquium about his research on the 4-5th of December 2017. Prof. Nasser has an impressive track record in biomarker discovery. His lab has a variety of biochemical tools which will be used in the cooperation as valuable benchmarking methods for the analysis of blood samples. Moreover Dr. Nasser has built up a large biorepository from more than tens of thousands of Arab children as well as tens of thousands of adults in Saudi Arabia. His great deal of expertise in biomarker research together with his biorepository might provide important contributions to testing the applicability of field-resolved infrared molecular fingerprinting for biomedical diagnostics of other chronic diseases, such as diabetes mellitus. The utility of this approach, which had been developed in the laboratories of Prof. Krausz, is currently being studied in another collaboration with Profs. Jean-Marc Nabholtz and Khalid Al-Saleh for early detection of breast cancer. Following his excellent talk, which was received with great interest, Prof. Nasser and Prof. Azzeer discussed possibilities of starting a collaboration in the above research direction. Prof. Nasser, Prof. Azzeer and Prof. Krausz agreed to continue discussions about a starting joint activities upon Prof. Krausz’ upcoming visit at KSU.

    Attosecond camera for nanostructures

    pressrelease — 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.

    Laser pulses: conductors for protons

    pressrelease — Light can conduct the play of atoms and molecules in the microcosm. Humans manage to interfere with this play. Researchers from the Laboratory of Attosecond Physics (LAP) of the Max Planck Institute of Quantum Optics (MPQ) and the Ludwig-Maximilians-Universität(LMU) and from the Department of Chemistry at the LMU have now used light to reconfigure hydrocarbons. Using ultrashort laser pulses they removed an outer hydrogen atom from one side of a hydrocarbon molecule and directed it to the opposite side, where it reattached. The method could be used in the future to synthesize new substances by controlling chemical reactions.

    Laser Pulses For Cancer Detection

    pressrelease — 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.

    First isolated attosecond pulses in Saudi-Arabia

    short report — The science of ultrashort metrology in the Attosecond Science Laboratory (ASL) in Riyadh picks up speed. The German/Saudi-Arabian team of physicists led by Prof. Ferenc Krausz and Prof. Abdallah Azzeer produced as the first team in the Arabic World isolated attosecond pulses in the ASL laboratory of the King Saud University in Riyadh. A big success for ultrafast physics in Saudi-Arabia. Attosecond-short light flashes are used for taking photographs of electrons. The team plans to observe the dynamics of electrons in molecules in the time dimension of attoseconds in order to examine processes in molecules in photoemission. During photoemission electrons are knocked out of atoms by photons (i. e. by light). This process is a major cause of damages to living cells. Increased knowledge about photoemission is thus crucial not only for physics, but also for medicine.

    Spotlight on Early Cancer Detection with Lasers (ECDL) – workshop at MPQ Garching

    short report — It would be tremendously beneficial to develop ways to detect and tackle cancerous development at a much earlier stage of the disease than is presently possible. Last week on June 11th and 12th 2015, a workshop was held at the Max Planck Institute of Quantum Optics (MPQ) to discuss the latest advances, perspectives and challenges in the emerging research area of early cancer detection. The workshop served to discuss joint efforts by scientists from the fields of cutting-edge laser physics, cell biology, cancer medicine, biochemistry and bioinformatics from MPQ, Ludwig Maximilian University (LMU), University of Innsbruck (Austria) as well as King Saud University (Riyadh, Saudi Arabia). Joint inter-disciplinary efforts and new approaches are building a bridge between novel laser technologies and clinically relevant cancer detection. These collaborative efforts have the potential to provide a springboard to detect cancerous onset earlier than ever.

    Light control of bond breaking in symmetric molecules

    pressrelease — Chemical bonds between carbon and hydrogen atoms are amongst the strongest in nature and their selective breaking, in particular in symmetric molecules, is of interest to chemical synthesis and the development of new biologically active molecules. An international team of scientists has now demonstrated that ultrashort light pulses with perfectly controlled waveforms can selectively break C-H bonds in acetylene ions. The researchers demonstrated that a suitable choice of the laser-pulse waveform leads to breaking of the C-H bond on the left (or right) side of the symmetric H-C≡C-H molecule. The scientists propose that their results can be understood by a new quantum control mechanism based on light induced vibration (Nature Communications, DOI:10.1038/ncomms4800).

    Solid-state light-wave detector

    pressrelease — A team in the Laboratory for Attosecond Physics (LAP) at the Max-Planck-Institute of Quantum Optics has taken another step toward the achievement of complete control over the waveform of pulsed laser light. Together with colleagues based at LMU and the Technische Universität München (TUM), they have constructed a detector which provides a detailed picture of the waveforms of laser pulses that last for a few femtoseconds (1 fs = 10-15 seconds). Unlike conventional gas-phase detectors, this one is made of glass, and measures the flow of electric current between two electrodes that is generated when the electromagnetic field associated with the laser pulse impinges on the glass. The researchers can then deduce the precise waveform of the pulse from the properties of the induced current. Knowledge of the exact waveform of the femtosecond pulse in turn makes it possible to reproducibly generate light flashes that are a thousand times shorter – lasting only for attoseconds (1 as = 10-18 sec) – and can be used to study ultrafast processes at the molecular and atomic levels (Nature Photonics, DOI:10.1038/nphoton.2013.348, January 12, 2014).
