              *Photonics at extreme ultraviolet and soft x-ray wavelengths
on a table-top*

With wavelengths of a few to tens of nanometers extreme ultraviolet (EUV)
and soft x-ray (SXR) light is being exploited in a rapidly increasing
number of scientific and technological applications, from imaging to
spectroscopy, to the lithography of semiconductor chips with 13.5 nm
wavelength light. Recent advances in the generation of bright EUV/SXR laser
beams on a table top are opening unique opportunities to advance photonics
in this challenging and relatively unexplored region of the electromagnetic
spectrum. This presentation will review results of efforts at Colorado
State University on the generation and utilization of EUV/SXR lasers for
nanoscale imaging, nano-spectrometry imaging and nanopatterning. These
photonic applications are making possible the imaging of nanostructures and
their dynamics, the three dimensional nanoscale mapping of the chemical
composition of organic and inorganic materials, and the printing of
periodic arrays of nanoscale features error-free, providing new
opportunities to access and probe the nanoworld.
