Design of a sub 100-femtosecond X-ray streak camera

Optics InfoBase Conference Papers (2009)

Authors:

B Li, PP Rajeev, G Gregori, M Benetou, B Dobson, A Cavalleri, L Pickworth, P Lau, P Jaanimagi, F Read, J Lynn, D Neely

Abstract:

The temporal resolution of existing streak cameras are limited by electron transit time dispersion. Here we present a state-of-art design compensating this to achieve a breakthrough of 100fs time resolution. © 2009 OSA/CLEO/IQEC 2009.

Probing strongly correlated electron dynamics on extreme timescales

Journal of Physics: Conference Series 148 (2009)

Authors:

S Wall, H Ehrke, D Polli, D Brida, Y Tokura, H Okamoto, G Cerullo, A Cavalleri

Abstract:

We use sub-10 fs laser pulses in the visible and near IR region of the spectrum in order to probe the dynamics of photo-induced phase transitions on their characteristic timescales. We present results from two different cases: the 1D organic Mott insulator ET-F2TCNQ and the more complex, colossal magneto-resistive manganite, Pr0.7Ca0.3MnO 3. For the former, we find that the melting of the Mott state takes 20 fs, a timescale which is dictated by the electron tunnelling time, h/t. In comparison, the dynamics of the manganite show coupling to a 14 THz structural mode and a high frequency 30 THz mode, which we assign as an orbiton, a collective electronic excitation. © 2009 IOP Publishing Ltd.

The XUV monochromator for ultrashort pulses at ARTEMIS

Optics InfoBase Conference Papers (2009)

Authors:

F Frassetto, S Bonora, P Villoresi, L Poletto, E Springate, CA Froud, ICE Turcu, DS Wolff, JL Collier, SS Dhesi, A Cavalleri

Abstract:

The XUV monochromator for ultrashort pulses at the ARTEMIS beamline is presented. It adopts an innovative configuration with gratings in the off-plane mount. The design and characterization of the monochromator are discussed. © 2009 Optical Society of America.
