cell with atomic sodium vapors: a top view; b side view; c the diagram view of interacting beams,
polarization planes of which are turned relative to each other. Reprinted from [54] with permission
Fig. 1.36 Spectrograms produced when passing through sodium vapors of weak and powerful
beams (intensity relation is 1:15), polarization planes of which are turned relative to each other

of a weak beam. The observed effect could be observed especially strong near the
resonator (see Fig. 1.36c).
Additional experiments (see Fig. 1.36d, e) have shown that the effect under review
does not depend on the path difference (path difference is ≈5 mm) between interfering
beams, so it is not conditioned by light diffraction on the volume dynamic grating,
