Effect of inhomogeneous electric field intensities on stark echo formation

We show that it is possible to control the appearance time of the Stark echo response by varying the intensity of inhomogeneous electromagnetic fields. We found that when the system is exposed to nonresonant laser pulses with spatial inhomogeneity, we observe a shift of the Stark echo appearance time in the nanosecond range. © 2012 Springer Science+Business Media New York

Formation of a Stark echo when external nonresonance laser fields with spatial inhomogeneity have various relative orientations

This paper shows that the response time of a Stark echo can be controlled by varying the relative orientation of inhomogeneous electromagnetic fields. It is found that, if nonresonance laser pulses that are spatially inhomogeneous act on the system, a shift in the appearance time of a Stark echo is observed in the nanosecond range. © 2012 Optical Society of America

How the unequal spacing of the spectrum of a three-level system affects the formation of a stimulated photon echo

This paper discusses the correlation of inhomogeneous broadening at various frequency transitions in three-level systems and how it affects the intensity of the stimulated-photon-echo response. It is shown that the correlation coefficient of inhomogeneous broadening at two different energy transitions and the response intensity of the stimulated photon echo depends on the random interaction parameter m of an optical electron with the local field, which in turn depends on the unequal-spacing parameter of the spectrum of the system. © 2013 Optical Society of America

Formation of stimulated photon echo by nonresonant laser pulses

We have studied formation of a stimulated photon echo on exposure to nonresonant standing-wave laser pulses. We show that a slight difference between the wavelengths of the nonresonant laser pulses leads to the effect of locking the stimulated photon echo responses. © 2013 Springer Science+Business Media New York

The effect of uncorrelatedness of inhomogeneous broadening on the formation of transient optical processes in multilevel systems

The correlation of inhomogeneous broadening at various frequency transitions in three-level systems is investigated, as is its effect on the intensity of a stimulated photon echo. It is shown that the correlation coefficient of inhomogeneous broadening at two different transitions and the response intensity of the stimulated photon echo depend on the parameter of the random interaction of an optical electron with a local field, as well as on the distribution width of additional frequency shifts owing to a partial fixation of transition energies. In this case, an insignificant variation of the correlation coefficient results in a considerable decrease in the response intensity. © Pleiades Publishing, Ltd., 2012

EPR imaging study of paramagnetic centre distribution in thiokol-epoxy hermetics

The distribution of paramagnetic centres in carbon black filler in the interphase layer of the thiokol-epoxy hermetics on the border of brass or glass substrate was studied using EPR-imaging method. It was shown that the relative content of radicals decreases near the hermetic-"rigid" surface contact border. The thickness of the layer with a low concentration of radicals is estimated as 0.5±0.3 mm. The inhomogeneous distribution of radicals is more obvious in the case of hermetic hardening on a brass surface. These results are explained by a catalytic acceleration of the thiokol-epoxy polymerization reaction in the region of hermetic-metal surface contact. © 1996 Springer
