Characterizing Anomalous High-Harmonic Generation in Solids
Lun Yue, Mette B. Gaarde
Anomalous high-harmonic generation (HHG) arises in certain solids when irradiated by an intense laser field, as the result of a nonlinear perpendicular current akin to a Hall curre…
Attosecond synchronization of extreme ultraviolet high harmonics from crystals
Giulio Vampa, Jian Lu, Yong Sing You +7
The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength range. These observatio…
Polarization-control of absorption of virtual dressed-states in helium
Maurizio Reduzzi, Johan Hummert, Antoine Dubrouil +9
The extreme ultraviolet absorption spectrum of an atom is strongly modified in the presence of a synchronized intense infrared field. In this work we demonstrate control of the abs…
Spatio-temporal coupling of attosecond pulses
Hampus Wikmark, Chen Guo, Jan Vogelsang +12
The shortest light pulses produced to date are of the order of a few tens of attoseconds, with central frequencies in the extreme ultraviolet range and bandwidths exceeding tens of…
Ab-initio calculations of the linear and nonlinear susceptibilities of N, O, and air in the mid-infrared
Jeffrey M. Brown, Arnaud Couairon, Mette B. Gaarde
We present first-principles calculations of the linear and nonlinear susceptibilities of N, O, and air in the mid-infrared wavelength regime, from m. We extract th…
