Modification of the coherence of undulator radiation

Autor: D. L. White, O. R. Wood, A. A. MacDowell, B. LaFontaine, S. Spector, J. E. Bjorkholm

Publikováno v: Review of Scientific Instruments. 66:1930-1933

The spatial coherence of undulator radiation has been modified in a quantitative way, such that when imaging with undulator light of λ=14 nm, the resultant images do not have the usual coherent artifacts of ringing and speckle. To achieve this, we m

A molybdenum/silicon multilayer-coated 1:1 ring-field optic with a numerical aperture of 0.0835 is used to carry out soft-x-ray projection imaging with undulator radiation at 12.9 nm. An ideal optic of this type should be able to image 0.1-μm featur

Soft-x-ray projection lithography experiments using Schwarzschild imaging optics

Publikováno v: Applied optics. 32(34)

Soft-x-ray projection imaging is demonstrated by the use of 14-nm radiation from a laser plasma source and a single-surface multilayer-coated ellipsoidal condenser. Aberrations in the condenser and the Schwarzschild imaging objective are characterize

Talk for the Arthur Ashkin Honorary Symposium: The Man and His Science

Autor: John E. Bjorkholm

Publikováno v: Frontiers in Optics 2010/Laser Science XXVI.

I am fortunate to have worked closely with Art Ashkin for many years. In this talk I will reminisce about the man and his many accomplishments.

Publikováno v: Review of Scientific Instruments. 63:737-740

It has been shown that it is possible to produce near diffraction limited images with soft x rays of wavelength 13.8 nm using normal incidence Si/Mo‐multilayered coated optics. Initial experiments with a 20X reduction Schwarzschild optic produced f

EUVL System Patterning Performance

Autor: Patrick P. Naulleau, J. E. Bjorkholm, Manish Chandhok

The great promise of EUV lithography (EUVL) comes from its tremendous reduction in wavelength, small numerical apertures (NAs), and large operational k1 factors. The latter two parameters lead to the very important conclusion of long extendibility of

Projection imaging of 0.1-microm lines and spaces is demonstrated with a Mo/Si multilayer coated Schwarzschild objective and 14-nm illumination from a laser plasma source. This structure has been etched into a silicon wafer by using a trilevel resist

Proposal for optically cooling atoms to temperatures of the order of 10-6 K

Autor: S. N. G. Chu, Leo W. Hollberg, Arthur Ashkin, John E. Bjorkholm, James P. Gordon

Publikováno v: Optics letters. 11(2)

We propose a technique for cooling optically trapped atoms to microkelvin temperatures, and lower, by using the dipole force of resonance-radiation pressure.

Optical bistability based on self-focusing

Autor: Peter W. Smith, Alexander E. Kaplan, Walter J. Tomlinson, John E. Bjorkholm

Publikováno v: Optics letters. 6(7)

We experimentally demonstrate a fundamentally new type of intrinsic optical bistability that requires no resonant optical cavity. Operation is based on mutual self-focusing of counterpropagating laser beams in a nonlinear medium.
