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 ...

Jet-loaded cold atomic beam source for strontium
Review of Scientific Instruments, 2023 We report on the design and characterization of a cold atom source for strontium (Sr) based on a two-dimensional magneto-optical trap (MOT) that is directly loaded from the atom jet of a dispenser. We characterize the atom flux of the source by measuring the loading rate of a three-dimensional MOT.

XPS chemical state mapping in opto- and microelectronics [PDF]
EPJ Web of Conferences, 2022 The strength of XPS imaging lies in its ability to (i) locate small patterns on sample surface, and (ii) inform, with micrometric lateral resolution, about the chemical environment of the elements detected at the surface. In this context, strontium-based

Lifetimes of ultra-long-range strontium Rydberg molecules [PDF]
, 2015 The lifetimes of the lower-lying vibrational states of ultralong-range strontium Rydberg molecules comprising one ground-state 5s2 1S0 atom and one Rydberg atom in the 5s38s 3S1 state are reported. The molecules are created in an ultracold gas held in an

Applied Sciences, 2021 The self-comparison method is a powerful tool in the uncertainty evaluation of optical lattice clocks, but any drifts will cause a frequency offset between the two compared clock loops and thus lead to incorrect measurement result.

A transportable strontium optical lattice clock [PDF]
, 2014 We report on a transportable optical clock, based on laser-cooled strontium atoms trapped in an optical lattice. The experimental apparatus is composed of a compact source of ultra-cold strontium atoms including a compact cooling laser set-up and a ...

Microscopic Control and Detection of Ultracold Strontium in Optical-Tweezer Arrays
Physical Review X, 2018 Optical tweezers provide a versatile platform for the manipulation and detection of single atoms. Here, we use optical tweezers to demonstrate a set of tools for the microscopic control of atomic strontium, which has two valence electrons.

Cooling and trapping of atomic strontium
Journal of the Optical Society of America B, 2003 We present a detailed investigation of strontium magneto-optical trap (MOT) dynamics. Relevant physical quantities in the trap, such as temperature, atom number and density, and loss channels and lifetime, are explored with respect to various trap parameters.
