“…The homogeneous width of the F (2) 2 transition at room temperature and methane pressure within the limits of 10 −4 to 10 −1 Torr turns out to be rather narrow, and the transition itself has a fairly large absorption index per unit length. The features of the well-studied F (2) 2 transition [6] and the He-Ne gas mixture and wide experience in work with such media [7][8][9][10][11][12] determined the choice of the experimental setup. A layout of this setup is presented in Fig.…”

UDC 621.373Using the method of nonlinear polarization spectroscopy in the oppositely propagating laser beams of different power at a wavelength of 3.39 µm, we study, both theoretically and experimentally, the mechanisms of the formation of dichroism and birefringence during the interaction of arbitrarily polarized fields of resonant radiation with gaseous methane under conditions of low pressure of the gas in the cell and saturation of the operating transition F (2) 2 by the field of a strong wave. Spectral forms of the polarization resonances of the test-wave intensity at the output of the polarization spectrometer are studied experimentally. Based on the vector theory of light interaction with matter, we present an exhaustive theoretical interpretation of the experimental data on the dependence of the polarization state of a weak wave on the intensity of a linearly or circularly polarized high-power counterpropagating wave. A new technique of measuring the induced nonlinear anisotropy for test-field waves and the macroscopic parameters of the resonant gas is developed.

Usbact-Using the Boltzmam transfer equation and Maxwell's equation, an explicit expression has been obtained for third harmonic component in the reflected and transmitted waves from a magneto.plasmaslab when an electromagnetic wave of frequency w is incident normally onit. Theseexpressions for the third harmonic component in the reflected and transmitted waves have been used to obtain the optimum conditions under which the conversion efficiency of third harmonic is maximum. It is concluded that the efficiency of third harmonicconversionis maximumwhen Q,/w)z = 4.0, (Y&) = 10-5,
