Успешно проведена спектроскопия часового перехода, в ходе которой достигнута спектральная ширина линии перехода 12 Гц. Разработан измерительный комплекс на основе фемтосекундного синтезатора оптических частот. Измерительный комплекс позволяет сравнивать оптический репер частоты с водородным мазером. Созданный оптический репер частоты на холодных атомах 87Sr включён в состав Государственного первичного эталона единиц времени, частоты и национальной шкалы времени ГЭТ 1-2018.</p></abstract><trans-abstract xml:lang="en"><p>The results obtained during the development of an optical frequency standard, based on cold 87Sr atoms are presented. The parameters of experimental optical schemes developed for the realization of all stages of sequential laser cooling and trapping of 87Sr atoms into an optical lattice are described. Clock transition spectroscopy was successfully performed with a spectral transition linewidth of 12 Hz. A measuring scheme based on a femtosecond optical frequency synthesizer has been developed, which makes it possible to compare the optical standard with a hydrogen maser. The created optical frequency standard was included in the primary standard GET 1-2018.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптический стандарт частоты</kwd><kwd>холодные атомы</kwd><kwd>прецизионные измерения</kwd><kwd>лазерное охлаждение</kwd><kwd>спектроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical frequency standard</kwd><kwd>cold atoms</kwd><kwd>precision measurements</kwd><kwd>laser cooling</kwd><kwd>spectroscopy</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">Abgrall M., Chupin B., De Sarlo L., Guéna J., Laurent P., Le Coq Y., Le Targat R., Lodewyck J., Lours M., Rosenbusch P., Rovera G.
