Ultrafast modulation of x-rays using coherent phonons
Optics InfoBase Conference Papers (2001)
Abstract:
Time-resolved x-ray diffraction experiments are presented showing ultrafast modulation of anomalous transmission and recurrence of Pendellosung oscillations in thick crystals. These results are discussed in the context of coherent control and femtosecond x-ray pulse generation.Investigation of a hydrogen plasma waveguide.

Abstract:
A hydrogen plasma waveguide for high-intensity laser pulses is described. The guiding channel is formed by a small-scale discharge in a hydrogen-filled capillary. The measured lifetime of the capillary is inferred to be greater than 10(6) shots. The results of interferometric measurements of the electron density in the capillary are presented. The guiding channel is found to be highly ionized with an axial electron density of 2.7x10(18) cm(-3), and parabolic, the curvature corresponding to a matched spot-size of 37.5 microm.A Thomson scattering post-processor for the MEDUSA hydrocode
