Lattice motions from THz phonon polaritons measured with femtosecond X-ray diffraction

SPRINGER SERIES CHEM 88 (2007) 716-718

Authors:

A Cavalleri, S Wall, M Rini, C Simpson, N Dean, M Khalil, E Statz, DW Ward, KA Nelson, RW Shoenlein

Abstract:

We use femtosecond x-ray diffraction to measure the coherent lattice displacements associated with the excitation and propagation of THz phonon polaritons in LiTaO3.

Ultrafast gigantic photo-response in (EDO-TTF)(2)PF6 initiated by 10-fs laser pulses

SPRINGER SERIES CHEM 88 (2007) 621-623

Authors:

J Itatani, M Rini, A Cavalleri, K Onda, T Ishikawa, SY Koshihara, XF Shao, H Yamochi, G Saito, RW Shoenlein

Abstract:

We photo-excited a charge-ordered organic salt (EDO-TTF)(2)PF6 with sub- 10-fs optical pulses. The photo-induced metallic phase appeared within 80-fs after pumping, characterized by large changes in reflectivity (Delta R/R similar to 0.8) followed by strong coherent phonon modulation.

Time resolved conductivity dynamics in vanadium dioxide

Conference on Lasers and Electro Optics and 2006 Quantum Electronics and Laser Science Conference CLEO QELS 2006 (2006)

Authors:

DJ Hilton, RP Prasankumar, S Fourmaux, A Cavalleri, D Brassard, MA El Khakani, JC Kieffer, AJ Taylor, RD Averitt

Abstract:

Optical-pump terahertz-probe spectroscopy is used to investigate the photoinduced insulator-to-metal phase transition in vanadium dioxide. The observed dynamics are consistent with a spatially inhomogeneous insulating state. © 2005 Optical Society of America.
