In this contribution to celebrate'25 years of recollision physics', we reflect on how the
quantitative rescattering (QRS) theory was developed during the 2007–9 period. A short …

We study the ionization and high-order harmonic generation (HHG) in argon by short
linearly polarized laser pulses. We compare the populations of atomic orbitals and HHG …

The high-order harmonic generation (HHG) in xenon is studied by using the time-dependent
density-functional theory. The dynamics of all electrons on the outer 4th and 5th atomic …

We propose to use the generation of even Brunel harmonics (BHs) by optical laser pulses
for high-resolution gas-biased coherent detection of lower-frequency radiation in terahertz …

Using the analytic time-dependent effective range theory, we study two-color high-order
harmonic generation (HHG) involving a weak extreme ultraviolet (XUV) pulse and an …

We present an experimental technique using orbital angular momentum (OAM) in a
fundamental laser field to drive high harmonic generation (HHG). The mixing of beams with …

We present low-frequency approximation (LFA) for high-order harmonic generation (HHG)
process. LFA represents the lowest-order term of an expansion of the final-state interaction …

This chapter outlines the theory of atomic photoionization and the dynamics of the photon–
atom collision process. Those kinds of electron correlation that are most important in …

We report an extensive study of cross section, phase shift and time delay for H–Kr@ C 60
elastic scattering. To demonstrate the effect of encapsulation, we extend this study to H–C …

An analytic expression for the electron wave packet (EWP) describing high-order harmonic
generation (HHG) by atoms in an intense laser field with small ellipticity is derived quantum …
