Correlations drive the attosecond response of strongly-correlated insulators
Romain Cazali, Amina Alic, Matthieu Guer +8
Attosecond spectroscopy of materials has provided invaluable insight into light-driven coherent electron dynamics. However, attosecond spectroscopies have so far been focused on we…
Few-cycle optical vortices for strong field physics
Matthieu Guer, Martin Luttmann, Jean-François Hergott +3
We report on the generation of optical vortices with few-cycle pulse durations, 500J per pulse, at a repetition rate of 1 kHz. To do so, a 25 fs laser beam at 800 nm is shaped w…
Ultrafast Hidden Spin Polarization Dynamics of Bright and Dark Excitons in 2H-WSe
Mauro Fanciulli, David Bresteau, Jérome Gaudin +9
We performed spin-, time- and angle-resolved extreme ultraviolet photoemission spectroscopy (STARPES) of excitons prepared by photoexcitation of inversion-symmetric 2H-WSe with…
Spatio-temporal pulse cleaning in multi-pass cells
Jaismeen Kaur, Louis Daniault, Zhao Cheng +5
We study both numerically and experimentally the use of two third-order nonlinear temporal filtering techniques, namely nonlinear ellipse rotation (NER) and cross-polarized wave (X…
Single-stage few-cycle nonlinear compression of milliJoule energy Ti:Sa femtosecond pulses in a multipass cell
Louis Daniault, Zhao Cheng, Jaismeen Kaur +7
We report on the nonlinear temporal compression of mJ energy pulses from a Ti:Sa chirped pulse amplifier system in a multipass cell filled with argon. The pulses are compressed fro…
Anisotropic dynamics of two-photon ionization: An attosecond movie of photoemission
Alice Autuori, Dominique Platzer, Mariusz Lejman +15
Imaging in real time the complete dynamics of a process as fundamental as photoemission has long been out of reach due to the difficulty of combining attosecond temporal resolution…
In situ sub-50 attosecond active stabilization of the delay between infrared and extreme ultraviolet light pulses
Martin Luttmann, David Bresteau, Jean-François Hergott +2
The blooming of attosecond science (1 as = s) has raised the need to exquisitely control the delay between two ultrashort light pulses, one of them being intense and in…
Attosecond photoionization dynamics in the vicinity of the Cooper minima in argon
C. Alexandridi, D. Platzer, L. Barreau +15
Using a spectrally resolved electron interferometry technique, we measure photoionization time delays between the and subshells of argon over a large 34-eV energy range c…
Spin-, time- and angle-resolved photoemission spectroscopy on WTe
Mauro Fanciulli, Jakub Schusser, Min-I Lee +12
We combined a spin-resolved photoemission spectrometer with a high-harmonic generation (HHG) laser source in order to perform spin-, time- and angle-resolved photoemission spectros…
Original Ti:Sa 10 kHz Front-end design delivering 17 fs, 170 mrad CEP stabilized pulses up to 5 W
A. Golinelli, X. Chen, E. Gontier +6
We present a compact 10 kHz Ti:Sa front-end relying on an original double-crystal regenerative amplifier design. This new configuration optimizes the thermal heat load management,…
Evidence of resonant surface wave excitation in the relativistic regime through measurements of proton acceleration from grating targets
T. Ceccotti, V. Floquet, A. Sgattoni +25
The interaction of laser pulses with thin grating targets, having a periodic groove at the irradiated surface, has been experimentally investigated. Ultrahigh contrast ($\sim 10^{1…
An accurate optical lattice clock with 87Sr atoms
Rodolphe Le Targat, Xavier Baillard, Mathilde Fouché +4
We report a frequency measurement of the 1S0-3P0 transition of 87Sr atoms in an optical lattice clock. The frequency is determined to be 429 228 004 229 879 (5) Hz with a fractiona…
