Coherent radiation by two-level quantum systems with permanent dipole moments under multiphoton resonant laser excitation

H. K. Avetissian, B. R. Avchyan, G. F. Mkrtchian

The theory of coherent radiation emission in two-level quantum systems with permanent dipole moments at the multiphoton resonant excitation by moderately strong laser fields is presented. A simple analytic formula for the expectation value of a dipole moment operator is obtained. The spectrum corresponding to harmonic generation and low-frequency radiation on the generalized Rabi frequency is investigated both analytically and numerically. The effect of dynamic Stark shift on a dipole spectrum under direct multiphoton resonant excitation is considered.

Emission spectrum of two atoms interacting with two modes of the cavity field with different coupling constants through a multiphoton Raman process

Jian Feng, Song Tong-Qiang, Gao Yun-feng

The emission spectrum of a pair of effective two-level atoms interacting with two modes of the radiation field with different coupling constants through a multiphoton Raman process is studied. A general expression for the emission spectrum with two modes of the field being in arbitrary states is presented. Our results show that when two modes of the field are in arbitrary number states, the spectrum is always symmetric about the resonant frequency , although the Hamiltonian of the system is asymmetric which is induced by the two different atom-field coupling constants. This property is analysed with an analytic method.

Harmonics Generation on Three-Level Atomic Systems at the Multiphoton Resonant Interaction with Laser Fields

H. K. Avetissian, B. R. Avchyan, G. F. Mkrtchian

Coherent light scattering by a three-level atom due to multiphoton resonant excitation by laser radiation is studied towards the coherent shortwave radiation generation. The spectrum corresponding to harmonics generation is investigated both analytically and numerically.
