Polarization phenomena upon excitation by the Λ-scheme and at an anisotropic population of lower levels

Polarization characteristics of emission of an ensemble of atoms on coherent excitation in the presence of a strong magnetic field with allowance for the Doppler profile width

“…This study is a continuation of our investigation [7][8][9] of polarization characteristics of many-level coherently excited systems with low-lying levels excited by an axially symmetric interaction. In [7,8], we considered a system consisting of three isolated multiplets in the presence and in the absence of a weak magnetic field, with one of the multiplets being coherently populated from the other two.…”

“…The procedure for describing the polarization phenomena was considered in detail in our paper [7] and also in monograph [10]. Therefore, we only briefly discuss this problem.…”

“…In [7,8], we considered a system consisting of three isolated multiplets in the presence and in the absence of a weak magnetic field, with one of the multiplets being coherently populated from the other two. In contrast to the situation considered earlier, the low-lying multiplets of a system studied in [9] were separated by a narrow energy gap, with the external magnetic field acting on them being strong.…”
