Attosecond synchronization of extreme ultraviolet high harmonics from crystals Open
The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength range. These observations have opened up the possibility of attosecond metrology i…

Probing periodic potential of crystals via strong-field re-scattering Open
Strong-field ionization and re-scattering phenomena have been used to image angstrom-scale structures of isolated molecules in the gas phase. These methods typically make use of the anisotropic response of the participating molecular orbit…

Observation of backward high-harmonic emission from solids Open
We experimentally demonstrate backward emission of high-harmonics of a near-infrared laser from MgO and Si crystals in the direction of specular reflection. We show that the variation of the high-harmonic power with the angle of incidence …

Orientation dependence of temporal and spectral properties of high-order harmonics in solids Open
We investigate the connection between crystal symmetry and temporal and spectral properties of high-order harmonics in solids. We calculate the orientation-dependent harmonic spectrum driven by an intense, linearly polarized infrared laser…

High-harmonic generation in amorphous solids Open
High-harmonic generation in isolated atoms and molecules has been widely utilized in extreme ultraviolet photonics and attosecond pulse metrology. Recently, high-harmonic generation has been observed in solids, which could lead to importan…

Laser waveform control of extreme ultraviolet high harmonics from solids Open
Solid-state high-harmonic sources offer the possibility of compact, high-repetition-rate attosecond light emitters. However, the time structure of high harmonics must be characterized at the sub-cycle level. We use strong two-cycle laser p…

Observation of High-Harmonic Generation from an Atomically Thin Semiconductor Open
We report the observation of nonperturbative high-harmonic generation from monolayer MoS2. Here, the yield is higher in monolayer compared to a single layer of the bulk, an effect attributed to strong electron-hole interactions in the mono…
