“…Other schemes are possible using, for instance, up to three photodiodes to track the interferometer displacement. 58 In our case, the green laser beam enters the interferometer from the back side of the first BS (see top left BS and green lines in Fig. 2).…”

We describe the versatile features of the attosecond beamline recently installed at CEA-Saclay on the PLFA kHz laser. It combines a fine and very complete set of diagnostics enabling high harmonic spectroscopy (HHS) through the advanced characterization of the amplitude, phase, and polarization of the harmonic emission. It also allows a variety of photo-ionization experiments using magnetic bottle and COLTRIMS (COLd Target Recoil Ion Momentum Microscopy) electron spectrometers that may be used simultaneously, thanks to a two-foci configuration. Using both passive and active stabilization, special care was paid to the long term stability of the system to allow, using both experimental approaches, time resolved studies with attosecond precision, typically over several hours of acquisition times. As an illustration, applications to multi-orbital HHS and electron-ion coincidence time resolved spectroscopy are presented.

“…This requirement, combined with the long-acquisition times typical of coincidence measurements, represents a technical challenge for the implementation and development of attosecond coincidence spectroscopy. In many pump-probe measurements, a non-copropagating geometry, which requires an active stabilization setup [12][13][14][15][16][17], is used. This solution, however, adds complexity to the experimental apparatus.…”

We present a compact experimental setup for performing attosecond-pump-infrared-probe experiments with long-time delay stability. The robustness of the setup is demonstrated over a two-day acquisition time in two-photon photoionization of argon in the photon-energy range 17−33 eV. The propagation of the input infrared pulse, as driving pulse for the high-order harmonic generation process and for the generation of the sidebands of the main photoelectron peaks, through the main optical components is simulated and discussed. Our setup allows us to perform attosecond experiments with an overall stability of ± 40 as.

“…The advantage of this design is pumpprobe stability, because the delay between the XUV beam and near-infrared (NIR) beam is produced by only one optic: a combined XUV multilayer coated mirror and Ag coated mirror [8,[12][13][14]. Furthermore, the delay can be stabilized with an active feedback loop (stability of 46 as over 33 hours) in order to counteract any slow drifts [15]. In addition, the multilayer mirror can be designed to select specific attosecond frequencies.…”

The development of attosecond technology is one of the most significant recent achievements in the field of ultrafast optics; it opens up new frontiers in atomic and molecular spectroscopy and dynamics. A unique attosecond pumpprobe apparatus using a compact Mach-Zehnder interferometer is developed. The interferometer system is compact (∼290 cm 2) and completely located outside of the vacuum chamber. The location reduces the mechanical vibration from vacuum components such as turbopumps and roughing pumps. The stability of the interferometer is ∼50 as RMS over 24 hours, stabilized with an active feedback loop. The pump and probe fields can be easily altered to incorporate multiple colors. In the interferometer, double optical gating optics are arranged to generate isolated attosecond pulses with a supercontinuum spectrum. The frequencies of the attosecond pulses can be selected to be in the extreme ultraviolet (XUV) region (25-55 eV, 140 as) or the vacuum ultraviolet (VUV) region (15-24 eV, ∼400 as) by metal filters. Furthermore, the near infrared probe field (1.65 eV) can be upconverted to the ultraviolet (3.1 eV). The frequency tunability in the XUV and VUV is critical for selecting excited states of target atoms and molecules.
