28th April 2016: Quantum Swing - a pendulum that moves forward and backwards at the same time
Two-quantum oscillations of atoms in a semiconductor crystal are excited by ultrashort terahertz pulses. The terahertz waves radiated from the moving atoms are analyzed by a novel time-resolving method and demonstrate the non-classical character of large-amplitude atomic motions.. ...more.
22nd April 2016: Ultrafast photoelectron imaging grasps competition in molecular autoionization
Using time-, energy- and angular-resolved photoelectron imaging a team of researchers from the Max Born Institute in Berlin, in collaboration with colleagues from Milan and Padova, has been able to make snapshots of coupled Rydberg orbitals evolving in time during an ultrafast autoionization process.. ...more.

Thomas Elsaesser, Director at the Max-Born-Institute and Professor for Experimental Physics at Humboldt University, Berlin, receives the Ellis R. Lippincott Award for his "seminal contributions to the understanding of the ultrafast coherent and incoherent vibrational dynamics of hydrogen bonds in liquids and biomolecules". ...more.
18th February 2016: Amplification of Sound Waves at Extreme Frequencies
An electric current through a semiconductor nanostructure amplifies sound waves at ultrahigh frequency. This method allows for novel, highly compact sources of ultrasound, which can serve as diagnostic tool for imaging materials and biological structures with very high spatial resolution. ...more.
19th January 2016: Invisible light flash ignites nano-fireworks
A team of researchers from the Max Born Institute in Berlin and the University of Rostock demonstrated a new way to turn initially transparent nanoparticles suddenly into strong absorbers for intense laser light and let them explode. ...more.
22nd December 2015: Isolating Water's Impact on Vibrations within DNA
Researchers in Berlin have found that water at the interface with DNA contributes prominently to subpicosecond structure fluctuations, and leaves hydrogen bonds between DNA and water intact ...more.
9th December 2015: On the sad occasion of the death of Prof. Dr. Wolfgang Sandner
The Forschungsverbund Berlin e.V. (FVB) mourns the loss of laser physicist Prof. Dr. Wolfgang Sandner. On December 5th, he died unexpectedly at the age of 66. Wolfgang Sandner shaped the development of the Max-Born-Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) where he was one of the three directors from 1993 until 2013. ... more.
1st November 2015: On November 1st, Prof. Stefan Eisebitt has been appointed as W3-S-Professor in Laser Physics at the TU Berlin in combination with the position of a director at the Max-Born-Institute
Stefan Eisebitt studied physics in Cologne and carried out his research towards a M.Sc. thesis at the Institut für Festkörperforschung (IFF) of the Forschungszentrum Jülich. For his Ph.D. work, Eisebitt stayed for three years at the University of British Columbia, Canada, on a DAAD fellowship. His thesis, submitted 1996 to Cologne University, was focused on the interplay of geometric and electronic structure in nanoscale materials, employing XUV and soft x-ray spectroscopy. ... more.
15th October 2015: Energy exchange in highly ionized nanoparticles
Excited atoms often decay via the emission of radiation, a process that is known as fluorescence. A different scenario can emerge when an excited atom is surrounded by other excited atoms, ions and electrons. Such a situation is achieved when an intense laser pulse interacts with a nanoscale object. In this case, an excited atom can decay by transferring its excess energy to another particle in the environment ... more.
28th September 2015: Hot means slow: Electron plasma oscillations tuned down with light
Oscillations of an optically heated electron plasma depend sensitively on the plasma temperature. Ultrafast heating and cooling of a plasma in the semiconductor zinc oxide (ZnO) leads to pronounced shifts of plasma frequency, holding a strong potential for novel switching applications in optoelectronics. ... more.
18th August 2015: How to Flow Ultrathin Water Layers - A Liquid Flatjet for X-Ray Spectroscopy
A major advance in solution phase soft-x-ray spectroscopy has been achieved utilizing a new liquid flatjet system, paving the way for novel steady-state and time-resolved experiments ... more.
13th August 2015: A new approach towards solving mysteries of the interstellar medium
It is one of the most intriguing questions in astrochemistry: the mystery of the diffuse interstellar bands (DIBs), a collection of about 400 absorption bands that show up in spectra of light that reaches the earth after having traversed the interstellar medium. Despite intense research efforts over the last few decades, an assignment of the DIBs has remained elusive, although indications exist that they may arise from the presence of large hydrocarbon molecules in interstellar space. Recent experiments at the Max Born Institute lend novel credibility to this hypothesis. ... more.
5th August 2015: European researchers light the way towards top-level laser science and innovations
LASERLAB-EUROPE, the consortium of major European laser research organisations, enters a new phase of collaboration from 2015 until 2019. In a very competitive call the consortium has been successful in securing EC funding of 10 million euros in Horizon 2020. ... more.
29th June 2015: Probing molecular chirality on a sub-femtosecond timescale
New nonlinear all-optical method of detecting chiral molecules is proposed and demonstrated. It is a lot more sensitive than standard all-optical techniques and also allows for sub-femtosecond temporal resolution of chiral dynamics. ... more.
28th May 2015: Are rogue waves predictable?
A comparative analysis of rogue waves in different physical systems comes to the surprising conclusion that these rare events are not completely unpredictable. ... more.

The combination of ab-initio numerical experiments and theory shows that optical tunnelling of an electron from an atom can occur instantaneously. ... more.
10th April 2015: Rubicon fellowship for Geert Reitsma

24th March 2015: The exciting story of He atoms in strong laser fields
Astonishingly, the interaction of atoms with intense laser radiation does not necessarily lead to ionization but also to bound excited states. As investigated in a recent publication, H. Zimmermann and coworkers have experimentally confirmed predictions of a model that provides an intuitive understanding of why and how strong-field excitation happens. ... more.
24th March 2015: Classical or not? Physics of nanoplasmas
The interaction of an intense laser pulse with a nanometer-scale particle results in the generation of an expanding nanoplasma. In the past, nanoplasma dynamics were typically described by classical phenomena, like the thermal emission of electrons. In contrast, a new study on the interaction of intense near-infrared (NIR) laser pulses with molecular oxygen clusters now demonstrates that phenomena, which can only be described quantummechanically, play an important role. ... more.
11th February 2015: New Insights into the photophysics of the DNA base thymin
DNA stores our genetic code. Solar UV radiation has sufficiently high energy to basically break bonds of the DNA and thus cause DNA damage. Although DNA (e. g. in our skin cells) is exposed to intense UV light irradiation, DNA proves to be surprising photostable. ... more.
