Femtosecond time-resolved X-ray diffraction study of ultrafast structural dynamics in laser-excited solids

Optics Infobase Conference Papers (2002) 19-20

Authors:

K Sokolowski-Tinten, C Blome, C Dietrich, J Blums, M Horn-Von-Hoegen, D von der Linde, A Cavalleri, J Squier, M Kammler

Abstract:

Time-resolved x-ray diffraction with sub-300 fs, multi-keV x-ray pulses was used to study ultrafast lattice dynamics in laser-irradiated germanium and bismuth. In bismuth strong excitation of optical phonons is observed prior to disordering of the material.

Femtosecond x-ray diffraction of short-pulse irradiated semiconductors

Pacific Rim Conference on Lasers and Electro-Optics, CLEO - Technical Digest (2002) 297-298

Authors:

CW Siders, A Cavalleri, C Tóth, KR Wilson, JA Squier, CPJ Barty, M Kammler, K Sokolowski-Tinten, M Horn von Hoegen, D Von der Linde

Abstract:

Femtosecond X-ray diffraction of short-pulse irradiated semiconductors was discussed. Ultrafast non-thermal solid-to-liquid transition in thin single-crystal Ge-111 films grown on Si-111 substrates were also studied. Proposed 4th generation light sources based upon single-pass x-ray free-electron lasers permitted single-shot structural determination of complex biomolecules.

Structural dynamics in laser-excited solids investigated with femtosecond x-ray diffraction

Pacific Rim Conference on Lasers and Electro-Optics, CLEO - Technical Digest (2002) 300

Authors:

K Sokolowski-Tinten, C Blome, C Dietrich, J Blums, M Horn-Von-Hoegen, D Von der Linde, A Cavalleri, J Squier, M Kammler

Abstract:

Structural dynamics in laser-excited solids were investigated with femtosecond X-ray diffraction. Lattice dynamics in a semi-metal, bismuth was studied. Results of transient changes of diffraction from (111) lattice planes of a 90 nm Bi film for three different laser fluences were shown.
