Sensing light

Future electronics will be fast. It could be driven at the frequencies of light waves. This implies that the switching speeds would be roughly 100,000 times faster than today. The development of electronics driven by light requires a detailed characterization of the light waves’s electromagnetic fields. Modern so-called field-sampling methods allow for probing the temporal […]

Exploration of new frequency frontiers

If physicists want to learn more about the dynamics of electrons in solids, they probe them with electromagnetic fields. A particularly powerful method is transient field-resolved spectroscopy. When a laser pulse excites electrons in a solid, its transmission or reflectivity changes. Transient field-resolved spectroscopy permits to monitor these changes after the excitation in the waveform […]

Trihydrogen formation by intense irradiation

The Ultrafast Imaging and Nanophotonics team, led by Prof. Matthias Kling, in collaboration with the American University Sharjah, reports a new route to the formation of trihydrogen ions (H3+). The route involves a bimolecular reaction between water molecules adsorbed on nanoparticle surfaces, a situation that closely mimics irradiated ice and ice/dust particles in outer space. […]

Poster award for Najd Altwaijry

At this year’s Max Planck School of Photonics Spring School Conference, Najd Altwaijry won a poster award. Her poster, titled: “Small, cheap method to sample electric fields up to 1PHz” included a 5-min video and explained the technique of “Nonlinear Photoconductive Sampling”. Using this technique, the team managed to sample an extremely short pulse (2,8fs) […]

X-ray Light in Overdrive

An international collaboration, with physicists from the Ludwig-Maximilians-Universität  Munich, the Max Planck Institute of Quantum Optics, and the King-Saud University in Riyad, has shown attosecond pulse generation under extreme conditions. The generation of coherent x-ray light by high-harmonic generation (HHG) with strong laser pulses is one of the major building blocks of attosecond science. It […]

Illustration of the experiment to measure the electromagnetic field of a light wave: the light wave (orange) is overlapped with a gating pulse (blue). Both pulses are focused into the air gap between two metallic electrodes, where they create a plasma spark.

Ultrafast Oscillation of Light Waves Unveiled in Plasma Spark

A German-Canadian collaboration, with physicists from the Ludwig-Maximilians-University Munich, the Max Planck Institute of Quantum Optics, and the Joint Attosecond Science Laboratory of the National Research Council and the University of Ottawa, has discovered a new way of tracing the ultrafast oscillations of the electric field in laser light waves. The electric field of a […]

Quantum brakes in molecules

Physicists of the Laboratory for Attosecond Physics have measured the flight times of electrons in molecules after their creation with light. The small quantum particles were emitted from a specific atom within the molecules, which enabled to measure the molecular influence on their emission time. The results open new opportunities to study the forces that […]
