Journal ArticleDOI
Tailored semiconductors for high-harmonic optoelectronics
Murat Sivis,Murat Sivis,Marco Taucer,Giulio Vampa,Kyle Johnston,André Staudte,Andrei Yu. Naumov,David M. Villeneuve,Claus Ropers,Paul B. Corkum +9 more
TL;DR: Nanofabricated structured targets of ZnO are used and varied the chemical composition of the sample to demonstrate that (modest) high harmonics can be generated as the light interacts with the target materials, and present the possibility of developing solid-state ultrafast optical devices.
Journal ArticleDOI
Ultrashort pulse non-linear optical absorption in transparent media.
TL;DR: It is demonstrated that non-linear absorption limits the intensity that can be reached and that the energy is deposited prior to the focus, and model the energy distribution, and predict and measure the energy transmitted through the focus.
Journal ArticleDOI
Oriented rotational wave-packet dynamics studies via high harmonic generation.
E. Frumker,E. Frumker,E. Frumker,Christoph T. Hebeisen,N. Kajumba,N. Kajumba,J. B. Bertrand,Hans Jakob Wörner,Hans Jakob Wörner,Michael Spanner,David M. Villeneuve,Andrei Yu. Naumov,Paul B. Corkum +12 more
TL;DR: Measurements reveal that, for the conditions optimum for harmonic generation, the orientation is produced by preferential ionization which depletes the sample of molecules of one orientation.
Journal ArticleDOI
Manipulation of quantum paths for space–time characterization of attosecond pulses
Kyung Taec Kim,Chunmei Zhang,Andrew D. Shiner,S. E. Kirkwood,E. Frumker,Genevieve Gariepy,Andrei Yu. Naumov,David M. Villeneuve,Paul B. Corkum +8 more
TL;DR: In this paper, an all-optical method to measure the space-time characteristics of an isolated attosecond pulse, without temporal and spatial averaging, is demonstrated, which may possibly be used to finely control the pulse characteristics.
Journal ArticleDOI
Probing Polar Molecules with High Harmonic Spectroscopy
E. Frumker,E. Frumker,E. Frumker,N. Kajumba,J. B. Bertrand,Hans Jakob Wörner,C. T. Hebeisen,Paul Hockett,Michael Spanner,Serguei Patchkovskii,Gerhard G. Paulus,David M. Villeneuve,Andrei Yu. Naumov,Paul B. Corkum +13 more
TL;DR: The methodology of orienting polar molecules is brought together with the phase sensitivity of high harmonic spectroscopy to experimentally compare the phase difference of attosecond bursts of radiation emitted upon electron recollision from different ends of a polar molecule.
