Optical Pumping advanced level Physics Experiments

The Optical Pumping of Rubidium Gas experiment is designed for advanced physics laboratories to investigate atomic energy levels, hyperfine interactions, and optical pumping phenomena using rubidium isotopes (Rb⁸⁵ and Rb⁸⁷). Students explore the interaction of atoms with light, radio frequency fields, and magnetic fields while studying atomic transitions, magnetic resonance, and quantum behavior. The system provides hands-on experience with modern atomic physics experiments and enables comparison of experimental results with theoretical predictions.
