An analysis is made of the difference magnetooptic signals in fluorescence induced by anisotropic collisions discussed in an earlier paper of the authors [Sov. J. Quantum Electron. 14, 703 (1984) ]. It is shown that different variants of the signals are described by different sets of anisotropic relaxation constants. Variants of signals optimal from the point of view of obtaining information separately on each of the anisotropic relaxation constants are determined.

An explanation has been found for the resonances which form in absorption dips in the output power of a wideband laser with an amplitude-anisotropic resonator containing a strongly absorbing atomic medium in a magnetic field. These resonances are caused by rotation of the polarization plane of the light in the medium. It is suggested that these resonances be used to measure high optical densities of media. This method has been used to experimentally determine the optical density of potassium vapor at the frequencies of the resonance doublet at various temperatures.

The absorption of a traveling elliptically polarized wave as a function of an external static magnetic field (magnetooptical resonance) is studied theoretically. An expression for the zero-field level-crossing signal is derived for the transition F = 0 → F = 1 and it is shown that, in the presence of dephasing collisions, the resonance may have a double structure.
