Paper Abstract

The coherent response accumulation method is used to assess the ability to amplify the polarization rotated component of a probe beam about two-photon resonance conditions. Atomic gas of alkaline metal atoms is chosen as a medium of interest. Probe wave connects the atomic ground state nS1/2 with the excited doublet nP1/2,3/2, which in its turn is coupled to the higher excited level n'S1/2 by an intense pump field. The relaxation processes and the Doppler effect are also included into the theory. It is shown that sequentially changing the input probe field's phase from 0 till and vice-versa, one can get about 2 times narrowing and more than 14 times amplification of intensity for the final part of rotated component of the probe wave.
