Считается, что излучение накачки распространяется в поперечном направлении через сравнительно узкую область этой ячейки. Проанализированы зависимости установленных внутридоплеровских резонансов от интенсивности и пространственного распределения такой оптической накачки. Предлагаемый метод спектроскопии высокого разрешения позволяет уменьшить доплеровское уширение регистрируемых резонансов флуоресценции на величину отношения диаметра газовой ячейки к сравнительно узкой ширине локальной области излучения накачки.</p></abstract><trans-abstract xml:lang="en"><p>New sub-Doppler fluorescence resonances at the central frequencies of atomic (molecular) transitions induced by stationary broadband optical pumping in a cylindrical cell with a rarefied gas medium are established and analyzed. The pump radiation is considered to propagate transversely through a relatively narrow region of this cell. The dependences of the established sub-Doppler resonances on the intensity and spatial distribution of such an optical pumping are analyzed. The proposed method of high-resolution spectroscopy allows one to reduce the Doppler broadening of the recorded fluorescence resonances by the value equal to the ratio of the gas cell diameter to the relatively narrow width of the local region of the pumping radiation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внутридоплеровские резонансы</kwd><kwd>флуоресценция атомов</kwd><kwd>локальная оптическая накачка</kwd><kwd>газовая ячейка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sub-Doppler resonances</kwd><kwd>atomic fluorescence</kwd><kwd>local optical pumping</kwd><kwd>gas cell</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">W.
