摘要：

The creation and detection of atomic polarization is examined theoretically through the study of basic optical-pumping mechanisms and absorption and fluorescence measurements and the dependence of these processes on the size of ground- and excited-state hyperfine splittings is determined. The consequences of this dependence are studied in more detail for the case of nonlinear magneto-optical rotation in the Faraday geometry (an effect requiring the creation and detection of rank-two polarization in the ground state) with alkali-metal atoms. Analytic formulas for the optical rotation signal under various experimental conditions are presented.
