“…This article may prove to be a valuable resource to current and forthcoming users as it showcases the technical capabilities at this impressive facility. On a different note, in the THz context, Mandal et al present a tutorial on the various techniques involved in producing attosecond delays well-suited for pump-probe studies involving an attosecond pulse synchronized with infrared, optical, ultraviolet or extreme ultraviolet pulses [55]. Techniques for metrology, spectroscopy and time-resolved studies both in the attosecond and THz domains are well represented in this collection.…”

This special issue of the European Journal of Physics: Special Topics entitled "Intense Laser Matter Interaction in Atoms, Finite Systems and Condensed Media" published a set of 21 articles aiming to put in perspective this burgeoning area of science, application and technology. The invention of chirped pulse amplification by Strickland and Mourou, which led to their Nobel prizes in 2018, has ushered in a new era in photon-matter interaction where coherent intense light pulses in the optical and infrared domains play a central role. This development has not only called in creative experimental methods, but has demanded new theoretical approaches working in the non-perturbative and highly nonlinear regimes of light-matter interaction. Both for fundamental physics as well as key applications these have played an essential role. Key pillars of this subject, captured in this collection, are laser-induced nanometerscale plasmas ignited in unsupported nanoparticles, laser-based particle acceleration taking advantage of unprecedented field gradients, the generation of high-order harmonics opening up attosecond science and ultrafast X-ray spectroscopy, and the generation of terahertz pulses for time-domain spectroscopy of new materials.

“…Optical delay lines are key tools in ultrafast science and technology with several applications from femtosecond metrology to attosecond pump-probe spectroscopy of matter [1][2][3][4][5][6][7] . Most delay lines are based on either amplitude division or wavefront division of an input beam.…”

“…All reflective delay lines are ideal to avoid pulse distortion caused by transmission of a short pulse through a medium. Several designs have been well established where wavefront division is achieved by a bisected split mirror using plane, spherical, parabolic, toroidal, and double-comb mirror 7,[17][18][19][20] in oblique as well as grazing incidence angle geometry 21 . Due to the grazing incidence of the input beam, the focus drifts away as one of the split mirrors is linearly displaced to control the delay, which limits the useful delay range to a few tens of fs.…”

We demonstrate a dispersion-free wavefront splitting attosecond resolved interferometric delay line for easy ultrafast metrology of broadband femtosecond pulses. Using a pair of knife-edge prisms, we symmetrically split and later recombine the two wavefronts with a few tens of attosecond resolution and stability and employ a single-pixel analysis of interference fringes with good contrast using a phone camera without any iris or nonlinear detector. Our all-reflective delay line is theoretically analyzed and experimentally validated by measuring 1 st and 2 nd order autocorrelations and the SHG-FROG trace of a NIR femtosecond pulse. Our setup is compact, offers attosecond stability with flexibility for independent beam-shaping of the two arms. Furthermore, we suggest that our compact and in-line setup can be employed for attosecond resolved pump-probe experiments of matter with few-cycle pulses.
