10 fs Pulses With Carrier-Envelope Phase Coherence

August 1, 2002
Author(s)
T M. Fortier, D J. Jones, Jun Ye, S T. Cundiff, R S. Windeler
The carrier-envelope phase of the pulse train emitted by a 10-fs mode-locked laser has been stabilized such that carrier-envelope phase coherence is maintained for a least 150 s (measurement limited). The phase coherence time was measured independent of

Dynamics in a Two-Level Atom Magneto-Optical Trap

July 1, 2002
Author(s)
X Xu, T Loftus, M J. Smith, John L. Hall, Alan Gallagher, Jun Ye
Alkaline earth metal atoms present an ideal platform for exploring magneto-optic trap (MOT) dynamics, enabling unique and definitive tests of laser cooling and trapping mechanisms. We have measured the trapping beam intensity, detuning, magnetic-field

Continuously Tunable Precise, Single Frequency Optical Signal Generator

June 1, 2002
Author(s)
J D. Jost, John L. Hall, Jun Ye
To realize a genuine CW optical frequency synthesizer, a continuously tunable single-frequency CW laser has been employed to track preciselyany arbitrary component of a wide bandwidth phase-stabilized optical comb. We dermnstrate in experiment two

Phase-Coherent Synthesis of Optical Frequencies and Waveforms

June 1, 2002
Author(s)
Jun Ye, Steven T. Cundiff, S M. Foreman, T M. Fortier, John L. Hall, K W. Holman, D J. Jones, J D. Jost, H C. Kapteyn, K A. Leeuwen, L -. Ma, M M. Murnane, J L. Peng, R K. Shelton
Precision phase control of an ultrawide-bandwidth optical-frequency comb has produced remarkable and unexpected progress in both areas of optical-frequency metrology and ultrafast optics. A frequency comb (with 100 MHz spacing) spanning an entire optical

Direct RF to Optical Frequency Measurements With a Femtosecond Laser Comb

April 1, 2002
Author(s)
Scott A. Diddams, D J. Jones, Jun Ye, S T. Cundiff, John L. Hall, J K. Ranka, R S. Windeler
By spanning an optical octave (> 300 THz) with a broadened femtosecond laser frequency comb, we directly measure optical frequency standards at 1064/532nm, 633 nm and 778 nm in terms of the microwave frequency that controls thecomb spacing, which can be

Sub-Doppler Molecular-Iodine Transitions Near the Dissociation Limit (523-498 NM)

April 1, 2002
Author(s)
W Y. Cheng, L Chen, T H. Yoon, John L. Hall, Jun Ye
A widely tunable and high-resolution spectrometer based on a frequency doubled Ti: sapphire laser is used to explore sub-Doppler transitions of iodine molecules in the wavelength range of 523-498 nm. The wavelength-dependence of the hyperfine transition

Issues and Applications in Ultrasensitive Molecular Spectroscopy

March 1, 2002
Author(s)
C Ishibashi, Jun Ye, John L. Hall
We present a systematic analysis of ultra-sensitive molecular detection methods based on an optical cavity and frequency modulation spectroscopy. Our goal is towards the improvement of the limiting attainable performance by the choice of optical

Subfemtosecond Timing Jitter Between Two Independent, Actively Synchronized Mode-Locked Lasers

March 1, 2002
Author(s)
R K. Shelton, S M. Foreman, L -. Ma, John L. Hall, H C. Kapteyn, M M. Murnane, M Notcutt, Jun Ye
With the implementation of a bandwidth servo, along with improved laser construction and associated better passive stability, we have achieved sub-femtosecond relative timing jitter between two independent, actively synchronized, mode-locked Ti-sapphire
