Always on beat: Ultrashort flashes of light under optical control

Ultrashort laser pulses have enabled scientists and physicians to carry out high-precision material analyses and medical procedures. Physicists from the University of Bayreuth and the University of Göttingen have now discovered ...

An ultrafast glimpse of the photochemistry of the atmosphere

Our lives are governed by submicroscopic processes in the nanocosmos. Indeed many natural phenomena begin with a minuscule shift in the states of atoms or molecules, triggered by radiation. One such process has now been elucidated ...

Could vacuum physics be revealed by laser-driven microbubbles?

A vacuum is generally thought to be nothing but empty space. But in fact, a vacuum is filled with virtual particle-antiparticle pairs of electrons and positrons that are continuously created and annihilated in unimaginably ...

Chemists give chance a helping hand

Whether they are synthetic materials such as PET and Teflon, medicines or flavourings, life without synthetically produced compounds is barely conceivable. The chemical industry depends on efficient, long-term methods of ...

Accurate probing of magnetism with light

Probing magnetic materials with extreme ultraviolet radiation allows to obtain a detailed microscopic picture of how magnetic systems interact with light—the fastest way to manipulate a magnetic material. A team of researchers ...

Peering into plasma mirrors

When light interacts with a mirror which is moving towards it at a speed close to the speed of light, its wavelength is shifted into the extreme ultraviolet region of the spectrum. This effect was first predicted by Albert ...

New method for better laser-material interaction

Using ultrashort laser pulses lasting a few picoseconds (trillionths of a second), Lawrence Livermore National Laboratory (LLNL) researchers have discovered an efficient mechanism for laser ablation (material removal) that ...
