We congratulate to the three winners of the 2023 Nobel Prize in Physics and we are extremely happy to have played a little role in the long path to this award. Indeed, one of the key experiments that led to today’s prize was performed in Florence, by Marco Bellini in collaboration with Ted Hänsch and …

We added time resolution to our laser fabricated 3D diamond detectors. See the paper in Nuclear Inst. and Methods in Physics Research, A for more info.

Intense laser pulses write graphitic electrodes in diamond in order to produce 3D pixel sensors optimised for timing applications at future hadron colliders. Just published in Instruments.

By measuring the tiny phase fluctuations between consecutive pulses from an infrared laser frequency comb we pose stringent limits to the extension of its spectroscopic and metrological applications towards the extreme ultraviolet. Just appeared in PRL.

We demonstrate a new scheme for performing Ramsey-type spectroscopy of XUV atomic transitions with high-order harmonics. Random time-sampling intervals are used to achieve absolute XUV frequency measurements at high accuracy and resolution.

We demonstrate the potential of a Ramsey spectroscopic scheme based on high-order harmonics to reach a resolving power >10^5 in the XUV. This is done by measuring clear quantum interferences in the excitation of an Argon transition at 87 nm for XUV pulse delays larger than 100 ps.

We demonstrate a simple technique for enhancing harmonic conversion yields by an array of gas interaction zones.

We have used an interferometric technique to directly measure the intrinsic nonlinear phase related to the different electronic trajectories involved in high-order harmonic generation in the XUV.
