Nonlinear interference effects in emission, absorption, and generation spectra
T. Ya. Popova, A. K. Popov, S. G. Rautian +1
Nonlinear effects in emission and absorption spectra of gaseous systems are considered. It is shown that level splitting can be detected spectroscopically even if it is below the D…
Resonant radiative processes
T. Ya. Popova, A. K. Popov, S. G. Rautian +1
The frequency correlation properties of the radiation from an atom in a strong field in resonance with neighboring transitions are considered. It is shown that the difference in fr…
Shape of the amplification line corresponding to an adjacent transition in a strong field
T. Ya. Popova, A. K. Popov
An analysis is made of the effect of a strong field on the shape of the amplification spectral line for mono-velocity V-type three-level atoms. There are three strong-field contrib…
Effect of resonance radiative processes on the amplification factor
T. Ya. Popova, A. K. Popov
Optimal conditions to acomplish amplification without inversion in three-level schemes based on quantum nonlinear interference effects are analyzed. Specific features of relaxation…
