SUMMARY:Harnessing Attosecond Science in the Quest for Coherent X-Rays
 \, Physics Department Colloquium\, Margaret Murnane\, JILA/UC-Boulder
DESCRIPTION:To generate coherent x-ray beams\, extreme nonlinear optic
 al techniques have succeeded in upshifting visible laser light into th
 e soft x-ray region of the spectrum. This ability has given us a new c
 oherent light source that spans a large spectral bandwidth\, with puls
 e durations on sub-femtosecond or attosecond (1 as=10-18 s) time-scale
 s. Equally intriguing is the fact that we have learned how to use ligh
 t to coherently manipulate electrons in atoms and molecules on their f
 undamental\, attosecond\, timescales. The richness and complexity of a
 ttosecond science and technology is only just beginning to be uncovere
 d. As I will discuss in this talk\, attosecond science can capture the
  complex\, interwoven dance of electrons in molecules and materials. A
 ttosecond science also shows great promise for developing new ultrasen
 sitive molecular imaging and spectroscopic techniques. Finally\, attos
 econd science represents the most promising avenue to achieve what had
  seemed hopelessly impractical until now -- the generation of bright\,
  coherent\, hard x-ray beams using a tabletop-scale apparatus.
