High flux strontium atom source

Quantum Science and Technology
Abstract We present a novel cold strontium atom source designed for quantum sensors. We optimized the deceleration process to capture a large velocity class of atoms emitted from an oven and achieved a compact and low-power setup capable of generating a high atomic flux.

Many-body correlations in one-dimensional optical lattices with alkaline-earth(-like) atoms

Scientific Reports, 2023
We explore the rich nature of correlations in the ground state of ultracold atoms trapped in state-dependent optical lattices. In particular, we consider interacting fermionic ytterbium or strontium atoms, realizing a two-orbital Hubbard model with two ...

Development of a strontium optical lattice clock for the SOC mission on the ISS [PDF]

, 2016
The ESA mission "Space Optical Clock" project aims at operating an optical lattice clock on the ISS in approximately 2023. The scientific goals of the mission are to perform tests of fundamental physics, to enable space-assisted relativistic geodesy and ...

An Evaluation of the Zeeman Shift of the ⁸⁷Sr Optical Lattice Clock at the National Time Service Center

Applied Sciences, 2020
The Zeeman shift plays an important role in the evaluation of optical lattice clocks since a strong bias magnetic field is applied for departing Zeeman sublevels and defining a quantization axis.

Experimental Observation of the Suppression of the Dephasing in a Floquet Engineering Optical Lattice Clock

Applied Sciences, 2022
Accurately manipulating quantum states is a fundamental strategy for improving the performance of quantum metrology, computing, and simulation. However, the quantum state is susceptible to dephasing due to the temperature and density of the atomic ...

Laser sources for precision spectroscopy on atomic strontium [PDF]

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2006
We present a new laser setup designed for high-precision spectroscopy on laser cooled atomic strontium. The system, which is entirely based on semiconductor laser sources, delivers 200 mW at 461 nm for cooling and trapping atomic strontium from a thermal source, 4 mW at 497 nm for optical pumping from the metastable P23 state, 12 mW at 689 nm on ...

Injection locking of a low cost high power laser diode at 461 nm [PDF]

, 2016
Stable laser sources at 461 nm are important for optical cooling of strontium atoms. In most existing experiments this wavelength is obtained by frequency doubling infrared lasers, since blue laser diodes either have low power or large emission ...

Modulation-free pump-probe spectroscopy of strontium atoms [PDF]

The European Physical Journal D, 2010
We have performed polarization spectroscopy and sub-Doppler DAVLL on the (5s5s) 1^S_0 -> (5s5p) 1^P_1 transition of atomic strontium. Both techniques generated a dispersion-type lineshape suitable for laser stabilization, without the need for frequency modulation.
