The spectral phase of high-order harmonic and attosecond pulses is typically shaped by the
interaction of the recollision electron with the strong field in the continuum. However, the …

Attosecond science and technology have emerged as a promising path for improving our
understanding of light–matter interaction. High harmonic generation based light sources …

High harmonic generation modulated by a weakly perturbing laser field enables new wave
mixing frequency components, thus allowing in-situ spatiotemporal measurements and …

High harmonic generation (HHG) modulated by a weak laser field allows the perturbative
wave mixing process which involves sum and difference frequency generations (SFG and …

Recollision physics and attosecond pulse generation meld the precision of optics with
collision physics. As a follow-up to our previous work, we reveal a new direction for the study …

Manipulation of ultrafast laser fields across the temporal, spatial, and spectral domains can
result in a spatiotemporally coupled structure of light, which cannot be mathematically …
