Предложен метод получения вихревых кольцевых пучков на основе диафрагмирования ВБП по первому минимуму распределения интенсивности. Показано, что эти пучки в сравнении с безвихревыми кольцевыми пучками той же мощности, формируемыми двухаксиконной схемой, характеризуются одним кольцевым максимумом в поперечном распределении интенсивности и подавленной дифракционной расходимостью осевого минимума. Установлено, что диафрагмирование ВБП по второму минимуму позволяет формировать световые пучки, дифракционное уширение осевого минимума которых оказывается пренебрежимо малым на расстояниях до сотен метров. Подавленное дифракционное расплывание осевого минимума на значительных расстояниях расширяет возможности практического применения предложенных вихревых кольцевых пучков в областях, где необходимо использование стабильных сингулярностей волнового поля, в частности, для квантового кодирования информации, передачи данных в свободном пространстве, а также для трехмерной  наноскопии. </p></abstract><trans-abstract xml:lang="en"><p>Vortex Bessel beams (VBBs) generated by an optical system consisting of two axicons with a small difference in cone angles and a spiral phase plate are studied using analytical and numerical methods. A method for producing vortex annular beams is proposed based on apexing the VBBs at the first minimum of the intensity distribution. It is shown that, compared to nonvortex annular beams of the same power generated by a two-axicon system, these beams are characterized by a single ring maximum in the transversal intensity distribution and suppressed diffraction divergence of the axial minimum. It is established that apexing the VBBs at the second minimum enables the formation of light beams whose diffraction broadening of the axial minimum is negligible at distances up to hundreds of meters. The suppressed diffraction broadening of the axial minimum dimensions at significant distances expands the possibilities of practical application of the proposed vortex ring beams to areas where stable singularities of the wave field are needed, in particular, for quantum information encoding, data transmission in free space, and for three-dimensional nanoscopy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптическое излучение</kwd><kwd>вихревой бесселев пучок</kwd><kwd>вихревой кольцевой пучок</kwd><kwd>аксикон</kwd><kwd>дифракционная расходимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical radiation</kwd><kwd>vortex Bessel light beam</kwd><kwd>vortex annular beams</kwd><kwd>axicon</kwd><kwd>diffraction divergence</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке в рамках проекта, совместно реализуемого образовательными и научными организациями России и Беларуси: грант  № 25-РБ-09-14 (Россия) и грант БРФФИ № Ф26СПбГ-003 (Беларусь).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">K.
