Terahertz (THz) waves have exhibited promising prospects in 6G/7G communications,
sensing, nondestructive detection, material modulation, and biomedical applications. With …

High-harmonic spectroscopy, an ultrafast all-optical technique initially conceptualized in
atomic and molecular systems, has now emerged as a powerful platform for studying the …

We demonstrate the generation of high-order harmonics of laser pulses in palladium and
cadmium plasmas. We adjusted the wavelength of driving pulses to investigate the …

We develop an approach to directly control the phase of an electron's sub-cycle motion in an
intense laser field. The method is established by tuning a low-frequency electric field applied …

We studied high-order harmonic generation (HHG) in graphene driven by either linearly or
elliptically polarized mid-infrared (MIR) light, and we additionally applied terahertz (THz) …

It is well known that a nontrivial Chern number results in quantized Hall conductance. What
is less known is that, generically, the Hall response can be dramatically different from its …

High (15–25) harmonic generation in the vacuum ultraviolet spectral range (83–50 nm) has
been realized by focused (NA= 0.033) near-infrared femtosecond laser radiation …

Although the frequency shift and odd-even intensity modulation in high-order harmonic
generation (HHG) have both been observed for asymmetric laser-target systems, they are …
