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.
