Molecular Iodine Clock

December 1, 2001
Author(s)
Jun Ye, L -. Ma, J L. Hall
We demonstrate a simple optical clock based on an optical transition of iodine molecules, providing a frequency stability stability superior to most rf sources. Combined with a femtosecond-laser-based optical comb to provide the phase coherent clock

Phase-Coherent Optical Pulse Synthesis From Separate Femtosecond Lasers

August 1, 2001
Author(s)
R K. Shelton, L -. Ma, H C. Kapteyn, M M. Murnane, John L. Hall, Jun Ye
We generated a coherently synthesized optical pulse from two independent mode-locked femtosecond lasers, providing a route to extend the coherent broadwidth available for ultrafast science. The two separate lasers (one centered at 760 nanometers wavelength

Cooling of a Single Atom in an Optical Trap Inside a Resonator

July 1, 2001
Author(s)
S J. van Enk, J McKeever, H J. Kimble, Jun Ye
We present detailed discussions of cooling and trapping mechanisms for an atom in an optical trap inside an optical cavity, as relevant to recent experiments. The interference pattern of cavity QED and trapping fields in space makes the trapping wells

A New Type of Frequency Chain and its Application to Fundamental Frequency Metrology

June 1, 2001
Author(s)
Thomas Udem, J Reichert, R Holzwarth, Scott Diddams, D J. Jones, Jun Ye, S T. Cundiff, T W. Hansch, John L. Hall
A suitable femtosecond (fs) laser system can provide a broad band comb of stable optical frequencies and thus can serve as an rf/opticalcoherent link. In this way we have performed a direct comparison of the 1 S - 2S transition in atomic hydrogen at 121 nm

High-Resolution Rb Two-Photon Spectroscopy With Ultrafast Lasers

May 1, 2001
Author(s)
T H. Yoon, A Marian, John L. Hall, Jun Ye
A two-photon wmsition in cold Rb atoms will be probed with a phase-coherent wide-bandwidth femtosecond laser comb. Frequency domainanalysis yields a high resolution picture where phase coherence among various transition pathways through different
