โœฆ Synopsis

The polarization properties of photon echoes in strong
magnetic field, when the action of this field during the time of
propagation of the exciting pulses and the echo signal through the
resonant gaseous medium cannot be neglected, are studied
theoretically. The photon echo polarization in strong magnetic
field cannot be described by the polarization vector but rather by
the polarization matrix. The degree of the photon echo
polarization decreases with the increase of the magnetic field
strength. The dependence of the photon echo intensity on the
magnetic field strength was also analyzed numerically. In strong
magnetic field the fast oscillations of this intensity appear to
be damping and modulated by the slower ones. The spectrum of these
oscillations depend also on the spectra of the exciting pulses, so
that in case of small area of the first exciting pulse its
temporal shape may be reconstructed from the oscillations of the
echo intensity versus the magnetic field strength.

The excitation of an N-level quantum oscillator by a strong oscillating electrtc fieId in the presence of external perturbations can in general be described by a Boltzmann equation for the density matrix. In this paper it is shown that under certain circumstances this may be reduced to a set of rate
