Multislit interference patterns in high-order harmonic generation in C60
We study high-order harmonic generation in C60 molecules interacting with a linearly polarized intense short laser pulse at nearand mid-infrared wavelengths, using an extension of the so-called three-step or Lewenstein model to the molecular case. The results exhibit modulations in the plateaus of the spectra at the longer wavelengths, which are present for ensembles of aligned as well as rando...
متن کاملBroadband Spectral Amplitude Control in High-Order Harmonic Generation
A technique for broadband spectral amplitude control of light pulses produced in high-order harmonic generation (HHG) is presented. It has been shown elsewhere that broadband spectral phase control in HHG is achievable using a computerized feedback loop scheme by coherently adding a filtered region of the HHG emission to the intense IR driving pulse with optimal attenuation and time delay param...
متن کاملHigh-Order Harmonic Generation from Molecules
Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. High harmonic generation in atoms is well understood in terms of the three step model (ionization, propagation and recombination), and much attention has been payed to the dynamics of t...
متن کاملSpectral Shifts of Nonadiabatic High-Order Harmonic Generation
High-order harmonic generation (HHG) is a nonlinear nonperturbative process in ultrashort intense laser-matter interaction. It is the main source of coherent attosecond (1 as = 10 s) laser pulses to investigate ultrafast electron dynamics. HHG has become an important table-top source covering a spectral range from infrared to extreme ultraviolet (XUV). One way to extend the cutoff energy of HHG...
متن کاملSecond harmonic microscopy of monolayer MoS2
We show that the lack of inversion symmetry in monolayer MoS2 allows strong optical second harmonic generation. The second harmonic of an 810-nm pulse is generated in a mechanically exfoliated monolayer, with a nonlinear susceptibility on the order of 10−7 m/V. The susceptibility reduces by a factor of seven in trilayers, and by about two orders of magnitude in even layers. A proof-of-principle...
