  • High resolution full-field imaging of nanostructures using compact extreme ultraviolet lasers
  • 2009
  • Ingår i: 9TH INTERNATIONAL CONFERENCE ON X-RAY MICROSCOPY. - : IOP Publishing.
  • Konferensbidrag (refereegranskat)abstract
    • Recent advances in the development of high peak brightness table-top extreme ultraviolet (EUV) and soft x-ray (SRX) lasers have opened new opportunities for the demonstration of compact full-field EUV/SXR microscopes capable of capturing images with short exposures down to a single laser shot. We demonstrate the practical application of table-top zone plate EUV microscopes that can image nanostructures with a spatial resolution of 54 nm and below and exposure times as short as 1.2 ns, the duration of a single laser shot.

  • Near-wavelength Resolution Extreme Ultraviolet Imaging With a Desktop-size Laser
  • 2008
  • Ingår i: 2008 CONFERENCE ON LASERS AND ELECTRO-OPTICS & QUANTUM ELECTRONICS AND LASER SCIENCE CONFERENCE, VOLS 1-9. ; , s. 400-401
  • Konferensbidrag (refereegranskat)abstract
    • We have realized the first demonstration of imaging in the extreme ultraviolet (EUV) with near-wavelength spatial resolution, 54 nm, using a uniquely compact full-field microscope that can produce images with a single one nanosecond exposure.

  • Single-shot extreme ultraviolet laser imaging of nanostructures with wavelength resolution
  • 2008
  • Ingår i: Optics Letters. - : Optical Society of America. - 0146-9592 .- 1539-4794. ; 33:5, s. 518-520
  • Tidskriftsartikel (refereegranskat)abstract
    • We have demonstrated near-wavelength resolution microscopy in the extreme ultraviolet. Images of 50 nm diameter nanotubes were obtained with a single ~1 ns duration pulse from a desktop-size 46.9 nm laser. We measured the modulation transfer function of the microscope for three different numerical aperture zone plate objectives, demonstrating that 54 nm half-period structures can be resolved. The combination of near-wavelength spatial resolution and high temporal resolution opens myriad opportunities in imaging, such as the ability to directly investigate dynamics of nanoscale structures.
