Stability measurements of the Ca and Yb Optical Frequency Standards

June 5, 2006
Author(s)
Christopher W. Oates, C Hoyt, Yann Le Coq, Zeb Barber, Tara M. Fortier, Jason Stalnaker, Scott A. Diddams, Leo W. Hollberg
In this paper we describe two types of optical atomic clocks. The first is based on freely expanding calcium atoms and is optimized for experimental simplicity and high stability. The second is based on Yb atoms confined to an optical lattice that is

Phase-stabilized ultrafast lasers signal new era in measurement and research

May 15, 2006
Author(s)
Tara M. Fortier, A Bartels, Scott A. Diddams
The development of short-pulsed lasers has progressed steadily over the past 30 years. In the search for better techniques and materials to generate shorter and shorter pulses, the 1990?s witnessed the arrival of Kerr-lens mode-locked Ti:sapphire lasers as

The development of short pulsed lasers has progressed steadily over the past 30 years. In the search for better techniques and materials to generate shorter and shorter pulses, the 1990's witnessed the arrival of Kerr-lens mode locked Ti:sapphire lasers as

Spectroscopy of a single Al + ion via coupling to Be +

July 25, 2005

Till P. Rosenband, Piet Schmidt, Jeroen Koelemeij, Wayne M. Itano, Yohei Kobayashi, Tara M. Fortier, Scott A. Diddams, James C. Bergquist, David J. Wineland
We perform precision spectroscopy on 27Al + with the aid of a 9Be + ion. Using sympathetic cooling and quantum state transfer, we efficiently interrogate the 1S 0 – 3P 1 and 1S 0 – 3P 0 transitions.

Femtosecond laser frequency combs: optical synthesizers for precision spectroscopy and frequency metrology

June 12, 2005
Author(s)
Scott A. Diddams, A Bartels, Tara M. Fortier, Eugene N. Ivanov, Kyoungsik Kim, John J. McFerran, Windell Oskay, G Wilpers, Christopher W. Oates, James C. Bergquist, Leo W. Hollberg, Vladislav Gerginov, C E. Tanner
A femtosecond laser frequency comb (FLFC) is the broadband (octave-spanning) evenly-spaced array of optical frequencies that is present in the output of a femtosecond mode-locked laser. Such frequency combs immediately found wide-spread use in optical
