SUMMARY
The discussion centers on the observation of polarization rotation in a Rubidium (Rb) vapor cell when subjected to a frequency-sweeping external cavity diode laser tuned to 384.229 Terahertz. A ramp voltage of 1 volt (peak-to-peak) is applied to a piezo, facilitating the tuning of various hyperfine transitions of rubidium. The experiment reveals a nonlinear increase in output intensity detected through a photodiode when the ramp amplitude is increased, suggesting a potential relationship with cyclotron resonance and sensitivity to magnetic fields in the Rubidium cell.
