High harmonic generation (HHG) in solid and gaseous targets has been proven to be a powerful avenue for the generation of attosecond pulses, whereas the influence of electron-phonon scattering on HHG is a critical outstanding problem. Here we first introduce a temperature dependent lattice vibration model by characterizing the spacing fluctuation. Our results reveal that (i) structural disorder induced by lattice vibration does not lead to generation of even-order harmonics; (ii) dephasing of HHG…

Ellipticity dependence of high-order harmonic generation in disordered semiconductors

We analyze the ellipticity dependence of high order harmonic generation (HHG) in disordered semiconductors. We show that a disordered crystal can radiated HHG spectra containing only odd harmonics of



Solid-state harmonics beyond the atomic limit

It is found that the high harmonic generation spectra from the rare-gas solids exhibit multiple plateaus extending well beyond the atomic limit of the corresponding gas-phase harmonics measured under similar conditions, suggesting the importance of electron–hole recollision in these solids.

Extreme–ultraviolet high–harmonic generation in liquids

The observation and detailed characterization of extreme ultraviolet HHG from liquid water and several alcohols extending beyond 20 eV is reported, which suggests liquid–phase high–harmonic spectroscopy as a new method for studying the electronic structure and ultrafast scattering processes in liquids.

Anisotropic high-harmonic generation in bulk crystals

High-harmonic generation in a solid turns out to be sensitive to the interatomic bonding — a very useful feature that could enable the all-optical imaging of the interatomic potential. The

Real-time observation of interfering crystal electrons in high-harmonic generation

This work studies high-harmonic generation in a bulk solid directly in the time domain, and reveals a new kind of strong-field excitation in the crystal that justifies the hope for all-optical band-structure reconstruction and lays the foundation for possible quantum logic operations at optical clock rates.

Linking high harmonics from gases and solids

It is found that solid-state high harmonics are perturbed by fields so weak that they are present in conventional electronic circuits, thus opening a route to integrate electronics with attosecond and high-harmonic technology.

High-harmonic generation in graphene enhanced by elliptically polarized light excitation

The observation of up to ninth-order harmonics in graphene excited by mid-infrared laser pulses at room temperature opens up the possibility of investigating strong-field and ultrafast dynamics and nonlinear behavior of massless Dirac fermions.

Using the third state of matter: high harmonic generation from liquid targets

High harmonic generation on solid and gaseous targets has been proven to be a powerful platform for the generation of attosecond pulses. Here we demonstrate a novel technique for the XUV generation

Extreme ultraviolet high-harmonic spectroscopy of solids

This study indicates the association of the emitted EUV radiation with intraband currents of multi-petahertz frequency, induced in the lowest conduction band of SiO2, and exploits the EUV spectra to gain access to fine details of the energy dispersion profile of the conductionBand that are as yet inaccessible by photoemission spectroscopy in wide-bandgap dielectrics.

Sub-cycle control of terahertz high-harmonic generation by dynamical Bloch oscillations

Terahertz waveforms with peak fields of 72 MV cm−1 and a central frequency of 30 THz drive interband polarization in bulk GaSe off-resonantly and accelerate excited electron–hole pairs, inducing

The temperature dependence of intermediate range oxygen-oxygen correlations in liquid water.

Analysis of temperature dependent oxygen-oxygen pair-distribution functions from experimental high-precision x-ray diffraction data of bulk water finds excellent agreement between simulations and experiment albeit with a temperature shift of ∼20 K and simulations of the TIP4P/2005 water model find excellent agreement.
