JILA Researchers have generated the most powerful XUV frequency comb yet. This tabletop experiment generates powers comparable to synchrotron light sources’, while maintaining stability and control. This tool could light a second revolution in quantum physics by enabling spectroscopy at unprecedented precisions.

 

With the advent of the laser, the fuzzy bands glowing from atoms transformed into narrow lines of distinct color. These spectral lines became guiding beacons visible from the quantum frontier.

More than a half century later, we stand at the next frontier. The elegant physics that will decode today’s mysteries (such as dark matter, dark energy, and the stability of our fundamental constants, to name a few) is still shrouded in shadows. But a new tool promises illumination. 

Whereas the monochrome glow of the laser illumed the mysteries of the quantum frontier, today’s frontier is lit by the frequency comb – a revolutionary laser source that emits not one, but over one-million distinct colors.

“Like the teeth of a comb that you could comb your hair with,” is how Stephen Schoun, a...
