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

July 17, 2021
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

Dipole-Dipole Frequency Shifts in Multilevel Atoms

June 30, 2021
Author(s)
Andre Cidrim, Asier Pineiro Orioli, Christian Sanner, Ross B. Hutson, Jun Ye, Romain Bachelard, Ana Maria Rey
Dipole-dipole interactions lead to frequency shifts which are expected to limit the performance of next generation atomic clocks. In this work, we compute dipolar frequency shifts accounting for the intrinsic atomic multilevel structure in standard Ramsey

Frequency Ratio Measurements with 18-Digit Accuracy Using a Network of Optical Clocks

March 24, 2021

Robinson, Stefania Romisch, Stefan A. Schaeffer, Jeffrey Sherman, Laura Sinclair, Lindsay I. Sonderhouse, William C. Swann, Jian Yao, Jun Ye, Xiaogang Zhang
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI system. By exploiting higher resonance frequencies, optical atomic clocks

Coherent light brightens the frontier of quantum science and technology

February 1, 2019
Author(s)
Jun Ye, Margaret Murnane
The precise control of coherent light across a vast spectral span has enabled revolutionary progress in precision measurements and the quantum control of atomic, molecular, and condensed matter systems. The laser was invented about 60 years ago (1) — 30
