Synchrotron Ultraviolet Radiation Facility SURF III

March 1, 2002
Author(s)
Uwe Arp, Charles W. Clark, Alex P. Farrell, E Fein, Mitchell L. Furst, Edward W. Hagley
The National Institute of Standards and Technology (NIST) has operated the Synchrotron Ultraviolet Radiation Facility (SURF) continuously since the early 1960s. The original accelerator was converted into a storage ring, called SURF II, in 1974. Then in

A High Speed Quantum Communication Testbed

Carl J. Williams, X Tang, M Hiekkero, J Rouzaud, R Lu, A Goedecke, Alan L. Migdall, A Mink, A Nakassis, Leticia S. Pibida, J Wen, Edward W. Hagley, Charles W. Clark

The Atom Laser

January 1, 2001
Author(s)
Edward W. Hagley, Lu Deng, William D. Phillips, K Burnett, Charles W. Clark

Imaging the Phase of an Evolving Bose-Einstein Condensate Wave Function

September 1, 2000
Author(s)
J E. Simsarian, J Denschlag, M Edwards, Charles W. Clark, Lu Deng, Edward W. Hagley, Kristian Helmerson, S L. Rolston, William D. Phillips
We demonstrate a spatially resolved autocorrelation measurement with a Bose-Einstein condensate (BEC) and measure the evolution of the spatial profile of its quantum mechanical phase. After releasing the BEC from the magnetic trap, the phase develops a

Coherence Properties of an Atom Laser

January 1, 2000
Author(s)
M Trippenbach, Y B. Band, M Edwards, M R. Doery, Paul S. Julienne, Edward W. Hagley, Lu Deng, M M. Kozuma, Kristian Helmerson, S L. Rolston, William D. Phillips
We study the coherence properties of an atom laser, which operates by extracting atoms from a gaseous Bose-Einstein condensate via a two-photon Raman process, by analyzing a recent experiment [(Hagley et al., submitted to Phys. Rev. Lett. (1999)]. We

Generating Solitons by Phase Engineering of a Bose-Einstein Condensate

January 1, 2000
Author(s)
J Denschlag, J E. Simsarian, D L. Feder, Charles W. Clark, L A. Collins, J Cubizolles, Lu Deng, Edward W. Hagley, Kristian Helmerson, W P. Reinhardt, S L. Rolston, B I. Schneider, William D. Phillips
We demonstrate quantum phase engineering using two novel techniques that allow us to write and read the spatial phase of a Bose-Einstein condensate (BEC). We design and produce a quantum state by optically imprinting phasepatterns onto a condensate of

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
