It is here presented the design and realization of a grazing-incidence grating monochromator for the spectral selection of ultrashort pulses in the extreme-ultraviolet, which preserves the duration of the pulse in the time scale of tens of femtosecon

Yield enhancement in multicolour high-order harmonic generation: Superposition of multiple un-related frequencies

Autor: I. Procino, R. Torres, Jonathan P. Marangos, Amelle Zaïr, Jonathan G. Underwood, T. Siegel, D. J. Hoffmann, Emma Springate, Leonardo Brugnera, Edmund Turcu, L. E. Chipperfield

Publikováno v: 2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC).

We report observations and analysis of high harmonic generation driven by a superposition of fields at 1290 nm and 780 nm. These fields are not commensurate in frequency, as in previous experiments such as Ref. [1], and the superposition leads to an

Single-grating monochromator for extreme-ultraviolet ultrashort pulses

Autor: C. A. Froud, I C Edmund Turcu, Paolo Villoresi, Fabio Frassetto, W. A. Bryan, Cephise Cacho, Luca Poletto, Emma Springate

Extreme-ultraviolet high-order-harmonic pulses with 1.6·10(7) photons/pulse at 32.5 eV have been separated from multiple harmonic orders by a time-preserving monochromator using a single grating in the off-plane mount. This grating geometry gives mi

Instantaneous Mapping of Coherently Coupled Electronic Transitions and Energy Transfers in a Photosynthetic Complex Using Angle-Resolved Coherent Optical Wave-Mixing

Publikováno v: Physical Review Letters. 102

Understanding the role of coherent electronic motion is expected to resolve general questions of importance in macromolecular energy transfer. We demonstrate a novel nonlinear optical method, angle-resolved coherent wave mixing, that separates out co
