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

Abstract

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.

The management of response time Stark echo and its intensity in the presence of non-resonant laser pulses with spatial inhomogeneity

“…Let us consider the scheme of Stark echo formation by a resonant laser pulse and the two non-resonant laser pulses with the same spatial inhomogeneity [3].…”

“…In [2], a possibility to control the appearance time of the Stark echo by varying the applied gradients of the external spatially inhomogeneous electric fields or their mutual orientation was shown. An analogous effect can be achieved using non-resonant interactions between the system and laser fields [3]. Non-resonant phenomena are associated with virtual transitions of an atomic electron.…”
