Vacuum technology makes gravitational waves detectable

You probably didn't notice the gravitational wave that propagated through the Earth in the early morning of Jan. 4, 2017, but thanks to a sophisticated use of vacuum technology, a pair of extremely sensitive laser interferometers, ...

Guiding the random laser

At its most basic level, a random laser is precisely what its name implies; random. It's random in the spectrum of light it produces and in the way that light is emitted, making what could be an extremely versatile laser ...

How photons change chemistry

The quantum nature of light usually does not play an important role when considering the chemical properties of atoms or molecules. In an article published in the Proceedings of the National Academy of Sciences scientists ...

Capturing an elusive spectrum of light

Researchers led by EPFL have built ultra-high quality optical cavities for the elusive mid-infrared spectral region, paving the way for new chemical and biological sensors, as well as promising technologies.

Transforming living cells into tiny lasers

In the last few decades, lasers have become an important part of our lives, with applications ranging from laser pointers and CD players to medical and research uses. Lasers typically have a very well-defined direction of ...
