“…Zeeman shifts of resonances in linear (discussed by, for example, Rikukawa et al, 1991) and nonlinear [Weis and Derler (1988); Ikegami et al (1989); Dinneen et al (1992); Lecomte et al (2000)] spectroscopy can be used for laser-frequency locking and tuning. Using nonlinear saturation spectroscopy, laser output is locked to a saturated absorption line whose frequency is modulated and shifted by a combination of ac and dc magnetic fields.…”

In this article, we review the history, current status, physical mechanisms, experimental methods, and applications of nonlinear magneto-optical effects in atomic vapors. We begin by describing the pioneering work of Macaluso and Corbino over a century ago on linear magneto-optical effects (in which the properties of the medium do not depend on the light power) in the vicinity of atomic resonances, and contrast these effects with various nonlinear magneto-optical phenomena that have been studied both theoretically and experimentally since the late 1960s. In recent years, the field of nonlinear magneto-optics has experienced a revival of interest that has led to a number of developments, including the observation of ultra-narrow (1-Hz) magneto-optical resonances, applications in sensitive magnetometry, nonlinear magneto-optical tomography, and the possibility of a search for parity- and time-reversal-invariance violation in atoms.Comment: 51 pages, 23 figures, to appear in Rev.

To date, frequency stabilization methods for semiconductor lasers mainly use the absorption line of an atom or molecule to modulate the frequency of laser light slightly so as to obtain a control signal. As a result, an oscillation bandwidth broadening will appear and the stabilization point will be restrained at the center frequency of the absorption line. This paper reports a frequency stabilization method using a magneto‐optical effect, the Faraday effect of an atomic absorption line, instead of direct modulation of the oscillation frequency. This stabilization method made it possible to control the stabilization point frequency by changing the dc magnetic field. With an Rb absorption line as the frequency reference, the controlled frequency range was about 1.5 GHz, which is wider than the Doppler width of the Rb absorption line at room temperature. The experimental results were consistent with the theoretical analysis.
