“…In order to handle the broad bandwidth and extreme average powers, the second MPC unit contained an array of dielectrically-enhanced silver-coated silicon mirrors that were actively cooled with water. Utilizing the same configuration, this group has recently reported the generation of CEP-stable 5.8 fs pulses with 107 W of average power at a repetition rate of 100 kHz [102]. Finally, MPC compression has been proposed and studied numerically for the compression of pulses from Ti:Sapphire systems with complex polarization states and Laguerre-Gaussian spatial modes [103,104].…”

Within the last two decades attosecond science has been established as a novel research ﬁeld providing insights into the ultrafast electron dynamics that follows a photoexcitation or photoionization process. Enabled by technological advances in ultrafast laser ampliﬁers, attosecond science has been in turn, a powerful engine driving the development of novel sources of intense ultrafast laser pulses. This article focuses on the development of high repetition rate laser-based sources delivering high energy pulses with a duration of only a few optical cycles, for applications in attosecond science. In particular, a high power, high repetition rate optical parametric chirped pulse ampliﬁcation system is described, which was developed to drive an attosecond pump-probe beamline targeting photoionization experiments with electron-ion coincidence detection at high acquisition rates.

We present the experimental realization of spectrally tunable, ultrashort, quasimonochromatic extreme ultraviolet (XUV) pulses generated at 100 kHz repetition rate in a user-oriented gas high harmonic generation (GHHG) beamline of the Extreme Light Infrastructure -Attosecond Light Pulse Source (ELI ALPS) facility. Versatile spectral and temporal shaping of the XUV pulses are accomplished with a double-grating, time-delay compensated monochromator accommodating the two composing stages in a novel, asymmetrical geometry. This configuration supports the achievement of high monochromatic XUV flux (2.8±0.9 × 10 10 photons/s) combined with ultrashort pulse duration (4.0±0.2 fs using 12.1±0.6 fs driving pulses) and small spot size (sub-100 µm). Focusability, spectral bandwidth, and overall photon flux of the produced radiation were investigated covering a wide range of instrumental configurations. Moreover, complete temporal (intensity and phase) characterization of the few-femtosecond monochromatic XUV pulses -a goal that is difficult to achieve by conventional reconstruction techniques -has been realized using ptychographic algorithm on experimentally recorded XUV-IR pump-probe traces. The presented results contribute to in-situ, time-resolved experiments accessing direct information on the electronic structure dynamics of novel target materials.

“…In a multi-pass cell (MPC) a laser pulse gets spectrally broadened due to the nonlinear effect of self-phase modulation (SPM). MPCs have successfully achieved compressions down to the few cycle regime [1,2], average powers greater than 1 kW [3] and compressibility of pulse energies higher than 100 mJ [4]. High power lasers are needed for the acceleration of particles in a plasma [5].…”

The temporal contrast of multi-pass cells can be increased significantly by implementing the technique of enhanced frequency chirping. By manipulating the pulse form using dispersive self-phase modulation the spectral modulations are reduced resulting in a pulse with decreased side-pulses and more energy in the main feature. Using MPC mirrors with a tailored dispersion and afterwards compensating accumulated higher order dispersions the energy ratio and peak power boost of a MPC can be improved notably.
