	abstract = {This manuscript presents the most recent upgrades made on SYLOS2 laser system in ELI-ALPS1. These modifications on the system were done based on the feedback from the experimental end-stations during the last 3 years. First, the long virtual propagation of the super-Gaussian output beam reduced by modifying the imaging telescope after the amplification stages, which significantly improved the beam profile hindered by the propagation-related diffraction pattern. The optical parametric chirped pulse amplification (OPCPA) stages were equipped with new nonlinear crystals which enabled to reach 42 mJ output energy with <8 fs pulse duration, which is 10 mJ more than the previous configuration. To increase the high-harmonic generation (HHG) efficiency a spatial filter was installed in the laser system which provides a nearly Gaussian beam profile at the output with 80% transmission. The spatial filter is based on a glass cone and is operated under vacuum. Currently, >20 mJ, <8 fs CEP-stable pulses are provided at the user stations after the beam transport system. © 2023 SPIE.},

The maximum energy of the protons reached ∼1.4 MeV accelerated in the laser propagation direction and ∼1.2 MeV in the opposite direction from a formvar target. The energy conversion efficiency from the laser to the proton beam is estimated to be as high as ∼1.4% at 45° laser incidence using a 51 nm thick Al target. The high laser contrast indicates the predominance of vacuum heating via Brunel’s effect as an absorption mechanism involving a tiny pre-plasma at the target front. The experimental results are in reasonable agreement with theoretical estimates, where proton acceleration from the target front side in the backward direction is well explained by the Coulomb explosion of a charged cavity formed in a tiny pre-plasma, while forward proton acceleration is likely to be a two-step process: protons are first accelerated in the target front-side cavity and then further boosted in energy through the target back side via the target normal sheath acceleration (TNSA) mechanism.},

By optimizing the input pulses in both spatial and temporal domains, after compression with customized chirped mirrors, we achieved pulses as short as 3.87 fs, in combination with 12-mJ energy. The spatio-spectral quality of the post-compressed pulses was thoroughly analyzed. The generated 1.4-cycle pulses pave the way for next generation attosecond and particle acceleration experiments.},
