Physics 111 Advanced Laboratory. Professor Dmitry Budker This is the second of two videos accompanying the Non-Linear Spectroscopy and Magneto-Optics Experiment, providing students with an introduction to the theory, apparatus, and procedures. The experiment consists of three sections: (1) students learn to operate a diode laser system and characterize its performance using a Fabry-Perot spectrum analyzer, (2) Doppler-broadened laser-induced fluorescence and Doppler-free saturated absorption spectra of the rubidium D2 line (780 nm) are recorded and analyzed, and (3) the near-resonant magneto-optical rotation is investigated. Nonlinear light-atom interaction leads to spectacular manifestations of the resonant Faraday Effect - polarization plane rotation in a magnetic field applied along the direction of light propagation radically different from the linear case. In particular, narrow (~30 Hz) effective line widths are observed in this experiment corresponding to a rotation enhancement by some seven orders of magnitude compared to the linear Faraday rotation. http://advancedlab.org
