“…We note in passing that each optical component of the complex setup depicted in Fig. 1 is equipped with in-vacuum motorisation for the various optical degrees of freedom, which sums up to a total amount of 37 translations and rotations being optimized as good as possible in the course of the commissioning [11,16].…”

“…The detailed specifications of the installed reflective optics are discussed in Refs. [11,16]. In the present DUV experiments, the outer mirror pair reducing the footprint on the mask was replaced by identical flat mirrors because of better overall reflectivity in the deep ultraviolet spectral range.…”

“…The characterization of spectral amplitudes and phases allows for control over the relative phase of a double pulse in time domain, which is created by a lamellar mirror assembly applied as shaping mask. In our previous research and development work on a prototypical setup, we focused predominately on simulating a theoretical auto-correlation signal of the DUV double pulses [11]. The present contribution goes beyond this by providing the all-optical characterization of amplitude and phase of the tailored waveform, both on the input as well as on the output side.…”

Controlling the temporal and spectral properties of ultrashort laser pulses in the visible and near-infrared spectral range by means of a femtosecond pulse-shaping device is a powerful tool with many applications in ultrafast spectroscopy. A major and successful concept is known as the 4f design, which has a symmetric zero-dispersion-compressor geometry. Most 4f pulse shapers rely on using transmissive optics in their beam path limiting the operational wavelength ranges. In the present contribution, we use an all-reflective shaping setup to generate a phase-locked 266 nm double pulse to benchmark its performance in the limit of short wavelengths. The setup comprises the complete spectral amplitude and phase diagnostics for quantitative analysis of the pulse properties before and after the shaper using the technique of frequency-resolved optical gating. The measured time–frequency spectra are in good agreement with optical simulations. The geometry and hardware of the device including the optical components are designed, such that all harmonics of the deep UV pulses travel the same path, giving the instrument the ability to work with soft X-ray pulses, under vacuum conditions, down to the few-nanometer wavelength scale.

“…In Ref [57]., an extreme ultraviolet pulse shaper has been built, which uses grazing-incidence reflective optics and operates under ultra-high vacuum, as shown in Figure 2. The instrument can shape femtosecond pulses with a wavelength as short as 15 nm, and a proof-of-principle experiment with 266 nm laser has been performed.…”

This review focuses on the properties of the light fields that are more useful in applications. We review recent means of generating shaped-pulse light field, by which matters can be steered toward the desired products, thereby allowing the coherent control in terms of effectiveness, selectivity and manipulation. Applications of these light fields are discussed, including bioscience, laser machining, novel material fabrication, trace material detection and military.

“…The implementation of XUV phase modulation via double-pulse seeding of HGHG has the advantage of avoiding the technical challenge of direct XUV pulse manipulation [23]. Instead, timing and phase properties of the seed pulses can be controlled to high precision acting on the UV pulses on the optical table [16,24].…”

High-gain harmonic generation with temporally overlapping seed pulses and application to ultrafast spectroscopy

Collinear double-pulse seeding of the High-Gain Harmonic Generation (HGHG) process in a free-electron laser (FEL) is a promising approach to facilitate various coherent nonlinear spectroscopy schemes in the extreme ultraviolet (XUV) spectral range. However, in collinear arrangements using a single nonlinear medium, temporally overlapping seed pulses may introduce nonlinear mixing signals that compromise the experiment at short time delays. Here, we investigate these effects in detail by extending the analysis described in a recent publication (Wituschek et al., Nat. Commun., 11, 883, 2020). High-order fringe-resolved autocorrelation and wave packet interferometry experiments at photon energies > 23 eV are performed, accompanied by numerical simulations. It turns out that both the autocorrelation and the wave-packet interferometry data are very sensitive to saturation effects and can thus be used to characterize saturation in the HGHG process. Our results further imply that time-resolved spectroscopy experiments are feasible even for time delays smaller than the seed pulse duration.
