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 1/ 2 nS with the excited doublet 1/ 2,3/ 2 nP , which in its turn is coupled to the higher excited level 1/ 2 n S c by an intense pump field. The relaxation processes and the Doppler effect are also included intodoi:10.1117/12.923615 fatcat:3pe7bbnjwrg4dphh7mqdmefm5y
