Welcome to the home page of the Extreme Light Group

We are a small group based in Florence, Italy, devoted to the experimental investigation of light and of its interactions at extreme conditions. “Extreme” refers both to the wavelengths and to the number of photons used in the experiments. Our research tools range from ultra-intense laser pulses to single photons, from ultra-broadband supercontinuum sources to radiation at the extreme ultraviolet (XUV) edge of the spectrum.

On one side, ultra-short and ultra-intense laser pulses are used to produce highly-nonlinear interactions with matter. This has led to fundamental studies on supercontinuum sources and frequency combs and to the production of coherent radiation in the XUV by high-order laser harmonics.

On the other, the ability to arbitrarily manipulate and characterize light at the single-photon level is allowing us to perform experiments on the foundations of quantum mechanics, and to develop exciting new tools for the emerging quantum technologies.

Besides these main activities, there are several others that you may discover by navigating this website. Be aware that it is still under construction, so come back regularly for updates.
