Imaging Lattice dynamics in individual nanocrystals

Optics InfoBase Conference Papers (2014)

Authors:

JN Clark, L Beitra, G Xiong, A Higginbotham, DM Fritz, HT Lemke, D Zhu, M Chollet, GJ Williams, M Messerschmidt, B Abbey, RJ Harder, AM Korsunsky, JS Wark, IK Robinson

Abstract:

We report imaging of coherent acoustic phonons on the picosecond time scale within a single nanocrystal using an X-ray free-electron laser. Our results allow unprecedented comparison with predictive models and observation of the vibrational modes. © 2014 OSA.

Order dependent spatial properties of high harmonic generation

Optics InfoBase Conference Papers (2014)

Authors:

DT Lloyd, K O'Keeffe, SM Hooker

Abstract:

We report on the dependence of the spatial properties of high harmonic generation on the harmonic order. We present interesting features in the transverse spatial coherence which may be important for coherent imaging experiments © OSA 2014.
