The availability of attosecond sources with high peak intensities has potential in opening new avenues for attosecond-pump/attosecond-probe studies of electronic processes in atomic and molecular physics, with interesting prospects in the field of coherent control of electronic motion in complex systems ...
This now is available uniquely at the Szeged Extreme Light Infrastructure–Attosecond Laser Pulse Source (ELI-ALPS). The to opposite side irradiation transfers no momentum to the target but the resonant absorption in the nanorod [3], which is parallel to the polarization of the laser light ...
we observe self-compression to sub-cycle pulses and infer the creation of sub-femtosecond field waveforms—a route to high-power optical attosecond pulse generation. Second, we efficiently generate continuously tunable high-energy (1–16 μJ) pulses in the vacuum and deep ultraviolet (110 nm...
rather than expensive synchrotron facilities. High-harmonic generation can also produce ultrashort light pulses, as short as one attosecond (10−18second) or maybe even one zeptosecond (10−21second), which are useful for
By using the high photon energies of HHG, the attosecond time delays between photoemission processes from core and valence electrons in bulk Cu, Ni, and W30,31,159 as well as in Mg/W(110) films151–153 have been identified. The high photon energy makes it also possible to study spin ...
Exceptions are time-resolved PES experiments using the reconstruction of attosecond beating by interference of two-photon transitions (RABBITT30–32), where an interference between photoexcitation by neighboring harmonics is required via an additional infrared excitation. Otherwise a monochromator, either ...
In this chapter we discuss the capabilities of the modern experimental physics of high energy densities to produce extreme states of matter in laboratory conditions. At the outset we briefly dwell on the main lines of investigations in this field. We nex
The experimental development of long wavelength light sources therefore holds great promise in many fields of science and will lead to numerous applications beyond strong field physics and attosecond science. In this paper, we present results about a high energy picosecond Holmium YLF laser developed ...

Developing compact ion accelerators using intense lasers is a very active area of research, motivated by a strong applicative potential in science, industry and healthcare. However, proposed applications in medical therapy, as well as in nuclear and part
