A possible strategy for a tabletop chiral attosecond laser

When molecules form from many atoms, the atoms can combine in different ways. Two forms of the same molecule can have the same composition but have different arrangements of atoms, giving rise to isomers. Some isomers may ...

Using diamonds to generate ultrashort THz pulses

The advent of intense ultrashort coherent light pulses has revolutionized the spectroscopy field. They allow easy observation of various nonlinear optical effects and facilitate the characterization of materials with nonlinear ...

Ultrafast control of spins in a microscope

Researchers at EPFL have developed a new technique that can visualize and control the rotation of a handful of spins arranged in a vortex-like texture at the fastest speed ever achieved. The breakthrough can advance "spintronics," ...

A new, better technology for X-ray laser pulses

The X-rays used to examine a broken leg in hospital are easy to produce. In industry, however, X-ray radiation of a completely different kind is needed—namely, X-ray laser pulses that are as short and high-energy as possible. ...
