| Abstract Title: |
W40 - Optical Pumping |
| Abstract: |
Optical Pumping is a classic advanced lab experiment that cleverly illustrates quantum mechanical angular momentum and selection rules. It uses circularly polarized light to create a ground state population distribution that is not in thermal equilibrium. Radio frequency (RF) stimulation can then drive the Zeeman sub levels back to equilibrium, and this is detected by a change in the optical transmission. This provides an amazing leverage in which one RF "photon" (f = 10 kHz to 5 MHz) can control the transmission of one light photon (f = 3.8 x 10 14 Hz)
Participants will:
• Identify the components and align the full optical path from source to detector.
• Use the Helmholtz coils to create a zero field situation, and observe the exquisite magnetic field sensitivity.
• Observe the Zeeman resonances and follow them up in field.
• Come back Friday to look at Rabi oscillations and multiple photon transitions. |
