Carrier-Envelope Phase Stabilization of Modelocked Lasers

October 12, 2021
Author(s)
T M. Fortier, D J. Jones, Scott Diddams, John L. Hall, Jun Ye, S T. Cundiff, R S. Windeler
Carrier-envelope phase stabilization of few cycle optical pulses has recently been realized. This advance in femtosecond technology is important in both extreme nonlinear optics and optical frequency metrology. The development of air-silica microstructure

Author(s)
D J. Jones, S T. Cundiff, T M. Fortier, J L. Hall, Jun Ye
The basic concepts, technical implementations, and known limitations of actively stabilizing the carrier-envelope phase of a few cycle pulse train are discussed. The route toward determining the absolute carrier-envelope phase, thereby enabling electronic

K W. Holman, R J. Jones, A Marian, S T. Cundiff, Jun Ye
We have performed systematic studies of intensity-related dynamics of the pulse repetition and carrier-envelope offset frequency in passively mode-locked Ti: sapphire lasers. We compare the results between two different repetion frequency laser systems

Colloquium: Femtosecond Optical Frequency Combs

October 12, 2021
Author(s)
S T. Cundiff, Jun Ye
Recently there has been a remarkable synergy between the technology of precision laser stabilization and modelocked ultrafast lasers. This has resulted in control of the frequency spectrum produced by modelocked lasers, which consists of a regular comb of

Control of the Frequency Comb From a Mode-Locked Erbium Doped Fiber Laser

October 12, 2021
Author(s)
J Rauschenberger, T M. Fortier, D J. Jones, Jun Ye, Steven T. Cundiff
We show that a stretched-pulse mode-locked fiber laser produces a well-defined frequency comb, providing a compact source of frequency combs and allowing comb-based optical frequency metrology to be extended into the 1.55 m region. This is achieved by

High Sensitivity CARS Microscopy With Two Tightly SynChronized Picosecond Lasers

October 12, 2021
Author(s)
J Potman, D J. Jones, J X. Cheng, X. Xie, Jun Ye
We demonstrate a significant improvement in signal-to-noise ratio recovered from coherent anti-Stokes Raman scattering (CARS) spectroscopy/microscopy, using two tightly synchronized picosecond Ti: sapphire lasers. A temporal jitter between the pulse trains

Author(s)
T M. Fortier, D J. Jones, Jun Ye, Steven T. Cundiff
We report on stabilizing the carrier-envelope phase of modelocked Ti:sapphire lasers. Optimization of the construction of the lasers for ease of phase stabilization is discussed. Results demonstrating long term phase coherence of the generated pulse train

T M. Fortier, Jun Ye, Steven T. Cundiff, R S. Windler
We present measurementsof the nonlinear phase noise generated in air-silica microstructure fiber, which is used in carrier envelope phase stabilization schemes for ultrafast lasers. The extreme nonlinearity exhibited by these fibers may result in amplitude

Optical Frequency Synthesis Based on Modelocked Lasers

October 12, 2021
Author(s)
S T. Cundiff, Jun Ye, John L. Hall
The synthesis of optical frequencies from the primary cesium microwave standard has traditionally been a difficult problem due to the large difference in frequencies. Recently a dramatic advance in this field has occurred due to the introduction of the use

Optical Pulse Synthesis From Two Separate Femtosecond Lasers

October 12, 2021
Author(s)
R K. Shelton, L -. Ma, H C. Kapteyn, M M. Murnane, J L. Hall, Jun Ye
Two independent mode-locked femtosecond lasers are tightly synchronized and phase locked. The rms timing jitter between the lasers is 4.3 fs within a 160 Hz bandwidth. The rms noise of the beat frequency between the two optical combs is 140 mHz at 1s

Picosecond Pulse Amplification With an External Passive Optical Cavity

October 12, 2021
Author(s)
E Potma, Christopher J. Evans, X. Xie, R. J. Jones, Jun Ye
We experimentally demonstrate the amplification of picosecond pulses at high repetition rates through coherent addition of successive pulses of a mode-locked pulse train in a high finesse optical cavity equipped with cavity dumping. Amplification greater

Three-dimensional dipolar thermalization in a reactive molecular gas with resonant shielding

October 1, 2021
Author(s)
Jun-Ru Li, William Tobias, Kyle Matsuda, Calder Miller, Giacomo Valtolina, Luigi De Marco, Rueben Wang, John Bohn, Goulven Quemener, Jun Ye
We demonstrate suppression of the reactive loss in a gas of ultracold 40K 87Rb molecules in a three-dimensional geometry. The electric field-induced collisional shielding suppresses loss by two orders of magnitude while preserving elastic, long-range

Detection and manipulation of the transverse motion in a Stark decelerator

Author(s)
Piotr Wcislo, Hao Wu, David Reens, Alexander Aeppli, Jun Ye
By enabling precise control over longitudinal velocity, Stark deceleration has become an important tool for studying cold collisions. However, the information about transverse motion is often hard to extract and to some extent beyond control. Here we
