New method measures super-fast, free electron laser pulses

New research shows how to measure the super-short bursts of high-frequency light emitted from free electron lasers (FELs). By using the light-induced ionization itself to create a femtosecond optical shutter, the technique ...

Modification of graphene using laser light

Graphene is an exciting new material, which has been characterized as a 'wonder material' because of its excellent properties. Graphene gained widespread attention in 2010 when the Nobel Prize in physics was awarded to researchers ...

Remote control for quantum emitters

In order to exploit the properties of quantum physics technologically, quantum objects and their interaction must be precisely controlled. In many cases, this is done using light. Researchers at the University of Innsbruck ...

Experiment reveals new options for synchrotron light sources

Accelerator experts from the Helmholtz-Zentrum Berlin (HZB), the German federal metrology institute Physikalisch-Technische Bundesanstalt (PTB) and Tsinghua University in Beijing have used a laser to manipulate electron bunches ...

Ultrafast electron dynamics in space and time

Often depicted as colorful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, ...

X-ray double flashes control atomic nuclei

A team of researchers from the Max Planck Institute for Nuclear Physics in Heidelberg has coherently controlled nuclear excitations using suitably shaped X-ray light for the first time. In the experiment performed at the ...

Switching nanolight on and off

A team of researchers led by Columbia University has developed a unique platform to program a layered crystal, producing imaging capabilities beyond common limits on demand.
