| Abstract: | In the rotating wave and slowly varying envelope approximations,the density-matrix motion equations for the three-level cascade system equation are solved under the influence of driving-field phase diffusion.The exact linear analytical solutions of the three-level cascade system with the driving field having the phase fluctuation in the steady state are obtained.The effects of phase diffusion on absorption,dispersion and population difference in a three-level upper-ladder system and on the time of steady-st... |
