Модуляция интенсивности возбуждения производилась в плоскости пленки, а генерация рассматривалась в направлении, перпендикулярном плоскости пленки. Диаметр генерирующей области выбирался на 1...2 порядка больше толщины пленки. В результате пространственно- модулированной накачки, наблюдалась пространственно-модулированная лазерная генерация. Сечение расходящегося лазерного луча пленочного лазера представляло собой интерференционную картину в виде светлых и темных полос, период которых определялся пространственным периодом накачки. Т. о, луч пленочного лазера нес информацию о пространственном распределении интенсивности накачки, а полученный пленочный лазер функционировал как активная элементарная динамическая голограмма.</p></abstract><trans-abstract xml:lang="en"><p>Peculiar properties of lasing from film dye lasers in the case of spatially modulated excitation are studied. The modulation of the excitation intensity in the plane of the film is performed and the laser emission perpendicular to the film plane is considered. The lasing area diameter is chosen 1...2 orders larger than the layer thickness. As a result of spatially modulated pumping, spatially modulated laser emission is observed. The cross section of the divergent laser beam represents an interference pattern in the form of light and dark stripes whose period depends on the spatial period of excitation. Thus, the beam of the film laser carries information about the spatial distribution of the pump intensity and the obtained film laser operates as an active elementary dynamic hologram.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерная генерация</kwd><kwd>пространственная модуляция интенсивности</kwd><kwd>динамическая голограмма</kwd><kwd>lasing</kwd><kwd>spatial modulation of intensity</kwd><kwd>dynamic hologram</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">Борн M., Вольф Э.
