Advances in Solid State Lasers Development and Applications
The interaction of high-intensity and ultrashort lasers with matter produces high energy particles and photons. Recent experiments include the generation of high quality GeV electron (Kneip et al., 2009; Leemans et al., 2006) and multi-MeV proton (Cl

We address the challenge of finding the optimal laser intensity and wavelength to drive high-energy, strong field rescattering and report the maximum yields of K-shell and L I -shell hole creation. Surprisingly, our results show laser-driven rescatte

We report photoelectron energy spectra and angular distributions for ionization with elastic scattering in ultrastrong laser fields. Noble gas species with Hartree–Fock scattering potentials show a reduction in elastic rescattering with the increas

Recollision for a laser driven atomic system is investigated in the relativistic regime via a strong field quantum description and Monte Carlo semiclassical approach. We find the relativistic recollision energy cutoff is independent of the ponderomot

Traditional laser-matter spectroscopy techniques fail to accurately analyze photoelectrons and ions from ultrahigh intensity studies with terawatt and petawatt laser systems. We present a magnetic deflection, photoelectron spectrometer for ultrahigh

Using a relativistic adaptation of a three-step recollision model we calculate photoelectron energy spectra for ionization with elastic scattering in ultrastrong laser fields up to 24 a.u. $(2\ifmmode\times\else\texttimes\fi{}{10}^{19}$ ${\mathrm{W}/

By driving the high harmonic generation process with multi-cycle mid-infrared laser pulses, we demonstrate bright isolated, attosecond soft X-ray pulses for the first time.

Ionization yields are reported for Ar, Kr and Xe in ultrastrong fields from 1015 W cm−2 to 1018 W cm−2. Non-sequential ionization (NSI) is shown to be a robust and general feature in ultrahigh field ionization. NSI yields measured are consistent
