Realization of High-Power Single-Frequency Continuous-Wave Tunable 689 nm Laser [PDF]

Micromachines
By analyzing the influence of the titanium–sapphire (Ti:S) crystal thermal effect on the laser resonator during the generation of a 689 nm laser, the thermal characteristics of the Ti:S crystal operating near the gain edge were investigated in this ...

A high flux source of cold strontium atoms [PDF]

The European Physical Journal D, 2015
We describe an experimental apparatus capable of achieving a high loading rate of strontium atoms in a magneto-optical trap operating in a high vacuum environment. A key innovation of this setup is a two dimensional magneto-optical trap deflector located

Magnetic trapping of metastable $^3P_2$ atomic strontium [PDF]

, 2002
We report the magnetic trapping of metastable $^3P_2$ atomic strontium. Atoms are cooled in a magneto-optical trap (MOT) operating on the dipole allowed $^1S_0-^1P_1$ transition at 461 nm.

Laser-induced thermal source for cold atoms

Scientific Reports, 2022
We demonstrate a simple and compact approach to laser cool and trap atoms based on laser-induced thermal ablation (LITA) of a pure solid granule. A rapid thermalisation of the granule leads to a fast recovery of the ultra-high vacuum condition required ...

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.

Steady-state magneto-optical trap of fermionic strontium on a narrow-line transition

Physical Review Research, 2021
A steady-state magneto-optical trap (MOT) of fermionic strontium atoms operating on the 7.5-kHz-wide ^{1}S_{0}-^{3}P_{1} transition is demonstrated. This MOT contains 8.4×10^{7}atoms, a loading rate of 1.3×10^{7}atoms/s, and an average temperature of ...

Demonstration of the Systematic Evaluation of an Optical Lattice Clock Using the Drift-Insensitive Self-Comparison Method

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.
