Progress on PARCS

Temporal, Matter-Wave Dispersion Talbot Effect

December 1, 1999
Author(s)
Lu Deng, Edward W. Hagley, J Denschlag, J E. Simsarian, M Edwards, Charles W. Clark, Kristian Helmerson, S L. Rolston, William D. Phillips
We analyze and experimentally demonstrate a new (temporal) Talbot effect, where a pulsed phase grating is applied to a cloud of cold atoms (Bose-Einstein condensate). In contrast to the usual (spatial) Talbot effect, our atoms gain kinetic energy when

Measurement of the Coherence of a Bose-Einstein Condensate

October 1, 1999
Author(s)
Edward W. Hagley, Lu Deng, M M. Kozuma, M Trippenbach, Y B. Band, M Edwards, M R. Doery, Paul S. Julienne, Kristian Helmerson, S L. Rolston, William D. Phillips
We study the coherence properties of a Bose-Einstein condensates using an interference technique. Two 100 ns optical standing wave pulses are applied to a condensate with a variable time delay between them. Each standing wave phase grating makes small

A Well Collimated Quasi-Continuous Atom Laser

March 1, 1999
Author(s)
Edward W. Hagley, Lu Deng, M M. Kozuma, J Wen, Kristian Helmerson, S L. Rolston, William D. Phillips
We demonstrate extraction of sodium atoms from a trapped Bose-Einstein condensate (BEC) using a coherent stimulated Raman process. Optical Raman pulses drive transitions between trapped and untrapped magnetic sublevels so as to give the output coupled BEC

Four-Wave Mixing With Matter Waves

March 1, 1999
Author(s)
Lu Deng, Edward W. Hagley, J Wen, M Trippenbach, Y B. Band, Paul S. Julienne, J E. Simsarian, Kristian Helmerson, S L. Rolston, William D. Phillips
The advent of the laser as an intense, coherent light source gave birth to nonlinear optics, which now plays an important role in many areas of science and technology. One of the first applications of nonlinear optics was the production of coherent light

Coherent Splitting of Bose-Einstein Condensed Atoms With Optically Induced Bragg Diffraction

February 1, 1999
Author(s)
M M. Kozuma, Lu Deng, Edward W. Hagley, J Wen, R Lutwak, Kristian Helmerson, S L. Rolston, William D. Phillips
We exposed Bose-Einstein condensed sodium atoms to a traveling periodic optical potential and observed coherent splitting of the condensate due to Bragg diffraction. Using the momentum selectivity of the scattering, we were able to separate a component

Smoothing a Current-Carrying Atomic Mirror

Self-Assembled Monolayers Exposed by Metastable Argon and Metastable Helium for Neutral Atom Lithography and Atomic Beam Imaging

September 1, 1997
Author(s)
A Bard, K K. Berggren, J L. Wilbur, John D. Gillaspy, S L. Rolston, Jabez J. McClelland, William D. Phillips, M Prentiss, G M. Whitesides
We used a beam of noble gas atoms in a metastable excited state to expose a thin (1.5nm self-assembled monolayer resist applied over a gold-coated silicon wafer. We determined exposure damage as a function of dose of metastable atoms by processing the

Atomic Collisions in Ultracold Atomic Gases

July 1, 1997
Author(s)
Paul S. Julienne, Kevin Jones, Paul D. Lett, William D. Phillips, Eite Tiesinga, U Volz, Carl J. Williams
Cold collisions between trapped atoms are very important in the context of Bose-Einstein condensation. The meaning of the scattering length, and its determination through the precision measurements of photoassociation spectroscopy, are described. This is
