Annotation
The population difference has been calculated for the levels in а twolevel atom in а strong field with allowance for the inelastic interaction with the dephasing noise, which modulates the transition fre quency; а saturating field means that there is the frequency - difference range in which the stationary population difference is inverted because of the asyrnmetry in the absorption and emission of the quanta responsible for the dephasing.
