Passively Mode-locked Glass Waveguide Laser with 14 fs Timing Jitter

December 1, 2003
Author(s)
John B. Schlager, Berton Callicoatt, Richard Mirin, Norman Sanford, David J. Jones, Jun Ye
Ultra-low jitter pulse trains are produced from a passively mode-locked erbium/ytterbium co-doped planar waveguide laser using high-bandwidth feedback control acting on the physical cavity length and optical pump power. Synchronization of a 750 MHz

Delivery of High Stability Optical and Microwave Frequency Standards Over an Optical Fiber Network

Jun Ye, J L. Peng, R J. Jones, K W. Holman, John L. Hall, D J. Jones, Scott A. Diddams, John E. Kitching, S Bize, James C. Bergquist, Leo W. Hollberg, Lennart Robertsson, L -. Ma
Optical and radio frequency standards located in JILA and NIST laboratories have been connected through a 6.9 km roundtrip optical fiber link. An optical frequency standard based on an Iodine stabilized Nd:YAG laser at 1064 nm with an instability of

Control of Coherent Light and its Broad Applications

Jun Ye, R J. Jones, K W. Holman, S M. Foreman, D J. Jones, S T. Cundiff, John L. Hall, T M. Fortier, A Marian
A remarkable synergy has been formed between the technology of precision optical frequency metrology and ultrafast laser science. This has resulted in control of the frequency spectrum produced by mode-locked lasers,which consists of a regular comb of

Cooling and Trapping of Atomic Strontium

May 1, 2003
Author(s)
X Xu, T Loftus, John L. Hall, Alan Gallagher, Jun Ye
We present a detailed investigation of the magneto-optical trap dynamics of alkarne-earth 88Sr atoms. The experimental results establish a firm confirmation of the laser cooling dynamics predicted by Doppler theory in thecontext of a strictly two-level

Single-Stage Sub-Doppler Cooling of Alkaline Earth Atoms

May 1, 2003
Author(s)
X Xu, T Loftus, J W. Dunn, C H. Greene, John L. Hall, Alan Gallagher, Jun Ye
We report the first experimental study of sub-Doppler cooling in alkaline earth atoms ( 87Sr) enabled by the presence of nuclear spin-oriented magnetic gedeneracy in the atomic ground state. Sub-Doppler cooling in a ς +-ς - configuration is achieved

Optical Frequency Standards and Measurement

April 1, 2003
Author(s)
John L. Hall, Jun Ye
This paper celebrates the progress in optical frequency standards and measurement, won by the 40 years of dedicated work of world-wide teams working in frequency standards and frequency measurement. Amazingly, after this time interval, the field is now
