Abstract

It is reported about the first experiments on the registration of a femtosecond time interval using the effect of non-Faraday rotation of the plane polarization of the stimulated photon echo. The experiment was performed at room temperature in a three-layer semiconductor film thickness of 300 nm, obtained by magnetron sputtering. The fundamental difference of this effect from the Faraday’s effect was shown. We give conclusions about the possibility of femtosecond time intervals registration at room temperature with an accuracy of 25 fs in the polarization principle of action, rather than spectral.

Highlights

The aim of the work is aimed at demonstrating the possibility of building on the basis of the effect of the new femtosecond magneto-optics principle of femtosecond time intervals registration
This principle of operation is used polarizing approach to fixing the value of these slotsTo achieve this goal have been made the work for the detection [1] and for quantitative assessment of non-Faraday rotation of the polarization plane of femtosecond stimulated photon echo
The effect, in contrast to the rotation of the polarization plane in optically active media and the Faraday rotation of the plane of polarization does not depend on the concentration of the growth of the active particles and the length of the path traversed by the radiation in resonance mediumAt the same time, the angle of rotation of the polarization plane of the echo signal φ defines by type of quantum transition and magnetic field produced by the amplitude and time delay between the exciting laser pulses
