        <p>Выполнено исследование спектральной зависимости нелинейного пленения излучения в атомных парах рубидия высокой плотности, где самоуширение резонансного перехода $5{ rm S}_{1/2}$--$5{ rm P}_{3/2}$ было больше доплеровского уширения. В эксперименте зарегистрирована ретро-флуоресценция, возбуждаемая узким лазерным пучком с диаметром 0.12~мм. Измерено эффективное время пленения излучения при различных интенсивностях лазерного пучка. Проведено краткое сравнение некоторых полученных результатов с данными из нашей публикации  mbox{2020 года}, где диаметр пучка был в полтора раза больше.  Предложены перспективные исследования атомных паров высокой плотности.</p>

        <p>We report a study of the spectral dependence of the nonlinear radiative trapping in high-density rubidium atomic vapor, where the self-extension of the $5{ rm S}_{1/2}$--$5{ rm P}_{3/2}$ resonance transition was larger than the Doppler broadening. In our experiment, retro-fluorescence excited by a narrow laser beam with a diameter of 0.12~mm was recorded. The effective emission trapping time at different laser beam intensities was measured. A brief comparison of some of the results obtained with data from our 2020 publication, where the beam diameter was one and a half times larger is summarized.  Prospective studies of high-density atomic vapor are proposed.</p>
