“…When the condition ( 16) is satisfied,the atomic model under consideration is equivalent to the two-level ground state substates system. Really, in this case in the equation ( 4) the standard reduction procedure to the ground state [18] can be made. The obtained equation system for the ground-state density matrix can be compared with the wellknown equations for a two-level atom [19].…”

The semiclassical theory of laser cooling is applied for the analysis of cooling of unbound atoms with the values of the ground and exited state angular moments 1/2 in a one-dimensional nondissipative optical lattice. We show that in the low-saturation limit with respect to the pumping field a qualitative interpretation of the cooling mechanisms can be made by the consideration of effective two-level system of the ground-state sublevels. It is clarified that in the limit of weak Raman transitions the cooling mechanism is similar to the Doppler mechanism, which is known in the theory of two-level atom. In the limit of strong Raman transitions the cooling mechanism is similar to the known Sisyphus mechanism. In the slow atom approximation the analytical expressions for the coefficients of friction, spontaneous and induced diffusion are given, and the kinetic temperature is estimated.PACS number(s): 32.80.

“…Let us recall several well-known examples. The resonant optical properties of an atomic medium with respect to a probe field are determined by the susceptibility tensor [8]. In the dipole approximation this tensor is expressed in terms of the multipole moments ρ K gg and/or ρ K ee of the ranks K ⩽ 2.…”

Steady-state multipole moments of atoms in a resonant field with elliptical polarization

et al. 2014

View full text Add to dashboard Cite

Steady-state multipole moments of atoms ρ K q of the rank K ⩽ 2 are analytically calculated for all closed dipole transitions J g → J e in a resonant radiation field with arbitrary intensity and arbitrary elliptical polarization. The nonlinear propagation of a monochromatic elliptically polarized wave through a medium consisting of atoms with resonant transition J g → J e is considered as an application.
