Time-resolved x-ray diffraction with picosecond time resolution is used to observe scattering from coherent acoustic phonons in laser-excited InSb crystals. The observed oscillations in the crystal reflectivity are in agreement with a model based on dynamical diffraction theory. Synchrotron radiation pulses of ∼300 fs in duration have been generated by femtosecond laser pulses modulating the electron beam in the Advanced Light Source. © 2000 American Institute of Physics.

    Abstract. We report on the diffraction of ultrashort laser pulses by single and double slits. The first-order diffraction was investigated as a function of the spectral bandwidth and the temporal duration of the laser pulses as well as a function of the pulse-front distortion. It is shown that a...

    The scalar problem of the propagation of a plane-wave pulse behind a diaphragm is solved. The calculation is performed on the basis of the nonstationary Kirchhoff-Sommerfeld integral and decomposition of the pulse in terms of wavelets. Two types of diaphragms, circular and square, are studied....

    In order to obtain reliable data on d values and integrated intensities, an imaging plate (IP) has been applied to high-pressure diffraction experiments with a diamond anvil cell using synchrotron radiation. The IP was found to be more effective than a conventional x-ray film by a factor of 30,...
