Dependence of the time of the appearance of a Stark echo response on irreversible relaxation of a system

Е. Н. Ахмедшина, L. A. Nefedev, Guzel I. Garnaeva

The dependence of the time of the appearance of a Stark (gradient) echo response on the irreversible transverse relaxation time of a system in the nanosecond range and on the width of the excitation region of an inhomogeneously broadened line has been investigated. It has been shown that the use of nonresonant laser pulses with an artificially created spatial inhomogeneity makes it possible to determine the relaxation time in the nanosecond range from the time of the appearance of a Stark (gradient) echo response, which is a more accurate method than the method of determining the relaxation time from the decay of the intensity by varying time intervals of the exposure to inhomogeneous electromagnetic fields.

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

Guzel I. Garnaeva, L. A. Nefedev, Е. Н. Ахмедшина

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.
