Fiber-laser frequency combs with subhertz relative linewidths

October 15, 2006
Author(s)
William C. Swann, John J. McFerran, Ian R. Coddington, Nathan R. Newbury, Ingmar Hartl, Martin E. Fermann, Paul S. Westbrook, Jeffrey W. Nicholson, K Feder, Carston Langrock, Martin M. Fejer
We investigate the comb linewidths of self-referenced, fiber-laser-based frequency combs by measuring the heterodyne beat signal between two independent frequency combs that are phase locked to a common cw optical reference. We demonstrate that the optical

Fiber Frequency Combs: Development and Applications

September 19, 2006

Nathan R. Newbury, William C. Swann, Ian R. Coddington, John J. McFerran
The output of a femtosecond fiber laser provides a comb of lines in frequency space that can be phase-locked to either a microwave or optical reference to form a stable frequency comb. We discuss the basic configuration of fiber laser-based frequency combs

Optical and microwave frequency synthesis with an integrated fiber frequency comb

June 5, 2006
Author(s)
Ingmar Hartl, Martin E. Fermann, William C. Swann, John J. McFerran, Ian R. Coddington, Qudsia Quraishi, Scott Diddams, Nathan R. Newbury, Carston Langrock, Martin M. Fejer, Paul S. Westbrook, Jeffrey W. Nicholson, K Feder
We demonstrate optical coherence over a broad spectral range of two independent fiber frequency combs. Additionally, we demonstrate microwave stability of better than 2x10 -14 in 1 second for an optically integrated fiber frequency comb.

Driving Bose-Einstein-Condensate Vorticity With a Rotating Normal Cloud

November 1, 2001
Author(s)
P C. Haljan, Ian R. Coddington, P Engels, Eric A. Cornell
We have developed an evaporative cooling technique that accelerates the circulation of an ultra-cold 87Rb gas, confined in a static harmonicpotential. As a normal gas is evaporatively spun up and cooled below quantum degeneracy, it is found to nucleate
