Laser Stabilization

February 19, 2017
Author(s)
John L. Hall, Jun Ye, M S. Taubman
It becomes clear that there are many interlinking considerations involved in the design of-laser stabilization systems, and it is difficult to present a full description in an article such as this. Still it is hoped that the reader will see some avenues to

Gas-phase broadband spectroscopy using active sources: progress, status, and applications

January 1, 2017
Author(s)
Kevin C. Cossel, Eleanor M. Waxman, Ian A. Finneran, Geoffery A. Blake, Jun Ye, Nathan R. Newbury
Broadband spectroscopy is an invaluable tool for measuring multiple gas-phase species simultaneously. In this work we review current applications for broad-band spectroscopy. We discuss components of broad-band spectroscopy including light sources

Progress on the Optical Lattice Clock

June 1, 2015
Author(s)
Andrew D. Ludlow, Jun Ye
We summarize recent research in the development of the optical lattice clock, with particular focus on the ytterbium and strontium lattice clocks being developed at NIST and JILA. We highlight recent progress in improving the stability and uncertainty of

Mid-Infrared Time-Resolved Frequency Comb Spectroscopy of Transient Free Radicals

June 10, 2014
Author(s)
Adam J. Fleisher, Bryce Bjork, Thinh Q. Bui, Kevin C. Cossel, Mitchio Okumura, Jun Ye
Quantitative measurements in chemical kinetics require unambiguous determinations of reactant, intermediate, and product concentrations on time scales faster than the reaction rate. Direct absorption spectroscopy in the mid-infrared (mid-IR) can fulfill

Probing interactions between ultracold fermions

April 17, 2009
Author(s)
G K. Campbell, M M. Boyd, J W. Thomsen, M J. Martin, S Blatt, M D. Swallows, Travis L. Nicholson, Tara Fortier, Christopher W. Oates, Scott Diddams, Nathan D. Lemke, Pascal Naidon, Paul S. Julienne, Jun Ye, Andrew Ludlow
At ultracold temperatures, the Pauli exclusion principle suppresses collisions between identical fermions. This has motivated the development of atomic clocks using fermionic isotopes. However, by probing an optical clock transition with thousands of

From Stable Lasers to Optical-Frequency Clocks

October 16, 2008
Author(s)
John L. Hall, Jun Ye, L -. Ma, J L. Peng, M Notcutt, J D. Jost, A Marian
This is a report on behalf of the World Tema of Stable Laser and Optical Frequency Measurement Enthusiasts, even if most detailed illustrations draw mainly from our work at JILA. Specifically we trace some of the key ideas that have led from the first

Optical Frequency Combs: From Frequency Metrology to Optical Phase Control

October 16, 2008
Author(s)
Jun Ye, H Schnatz, Leo W. Hollberg
A remarkable synergy between traditionally CW laser-based precision optical frequency metrology and mode-locked ultrafast lasers has led to precision control of the frequency spectrum produced by mode-locked lasers. Such a phase - controlled mode-locked

Optical Frequency Standards and Their Measurement

October 16, 2008
Author(s)
John L. Hall, Jun Ye
The last four years have seen a revolution in the art and practice of optical frequency measurement. Indeed the gearbox represented by the spectrally-broadened fs laser's comb has sufficiently low noise that we in the optics community have abruptly found

Optical frequency standards: Progress and applications

October 16, 2008
Author(s)
John L. Hall, Jun Ye, L -. Ma, K R. Vogel, Tim P. Dinneen
A number of individual small advances, taken together, bring us to the beginning of a new domain of optical frequency stability, reproducibility, and measurements. Particular advances include the refinment of Noise-Immune Cavity-Enhanced Optical Heterodyne
