An integrated high-flux cold atomic beam source for strontium.

Area of Science:

• Atomic Physics
• Quantum Optics
• Experimental Physics

Background:

• Developing compact and efficient cold atom sources is crucial for advancing quantum technologies.
• Traditional atomic beam sources often require large setups and significant power consumption.

Purpose of the Study:

• To design and characterize an integrated cold atomic beam source for strontium (Sr).
• To reduce the size and power requirements of atomic beam sources for strontium-based quantum devices.

Main Methods:

• Utilized a compact Zeeman slower with permanent magnets to cool a thermal atomic beam.
• Employed a two-stage, two-dimensional magneto-optical trap (MOT) atomic deflector to select and redirect cold atoms.
• Characterized the cold atomic beam flux by measuring the loading rate of a 3D MOT.

Main Results:

• Achieved cold strontium atoms with speeds below 50 m/s.
• The atomic deflector successfully redirected the cold flux by 20°.
• Measured loading rates of up to 10^9 atoms/s into a 3D MOT.

Conclusions:

• The developed source is compact, tunable, lightweight, and power-efficient.
• This integrated source simplifies the construction of strontium-based optical atomic clocks and quantum simulators.
• The design offers a practical solution for portable quantum technology applications.
