Principles of constructing a measuring current transformer based on photon echo

Anatolii N. Leukhin, Ivan I. Popov, Igor N. Polyakov

For a construction of the opto-electronic current transformer the effect of rotating of the photon echo (PE) polarization vector is offered. As an active ambience allowing get the photon echo the vapors of molecular iodine are used. The theoretical model of the opto-electronic current transformer (OECT) is discussed. The explanatory graphs of the n echo polarization vector rotating effect, as well as the principle scheme of the current measurement, are shown in the paper.

Physical measurings and quantum control in technique of a photon echo

Ivan I. Popov, Andrey M. Gladyshev, K.Sh. Gazizov

The effect of the rotating of the photon echo polarization vector is offered for a construction of the opto-electronic current transformer. As an active medium that allows get the photon echo the vapors of molecular iodine are used. The theoretical model of the opto-electronic current transformer is discussed. The results of investigation of photon echo (PE), excited by complexly coded laser pulses in molecular Iodine vapors under action of the homogeneous longitudinal magnetic field are given in this work. The recording possibility of special information by exciting pulses on a pair of quantum levels of resonant gas (molecular Iodine vapors) in technique PE is shown experimentally. In this shown experiment the information has two by two values of two relevant features and is represented by the amplitude-time shape and direction of linear polarization vector of radiation. The possibility of using the detected features of formation PE under the action of magnetic field for development the physical principles of the quantum control and for optical information processing introduced by hypercomplex number - quaternion - is shown.

Visual method of identification of the resonant transition

Ildus S. Bikbov, Ivan I. Popov, Anatolii N. Leukhin

Visual method of identification of the branch type of resonant transition is suggested in this paper. The method is basedon the measurement ofratio ofprimary photon echo amplitude to stimulated photon echo amplitude in the magnetic field,when the effect of non-Faraday rotation of the photon echo polarization vector is occurred. The experimental results ofidentification of the resonant transitions in the vapor of molecular iodine are demonstrated. The results were checked bythe measurement ofthe maximum rotation angle range ofprimary photon polarization vector. This parameter is similarlycharacterized the resonam transition. For the first time fact ofregistration ofthe non-Faraday rotation polarization vectorofstimulated echo, formed on the different resonant transitions (Q-branch or P(R)-hranch), is reported.Keywords: primary photon echo, stimulated photon echo, identification of the resonant transitions, non-Faraday rotationof the photon echo polarization, vapors of molecular iodine, magnetic field, Q -
