Продемонстрировано, что на вырожденном двухуровневом циклическом переходе  Fe &gt; Fg реализуется инверсная населенность между верхним и нижними зеемановскими подуровнями. Достигнута чувствительность (изменение) выходной мощности генерируемого излучения при изменении внешнего магнитного поля на ~70 нТл. Показано, что система может функционировать как металлоискатель, отмечено преимущество по сравнению с коммерческими металлоискателями.</p></abstract><trans-abstract xml:lang="en"><p>A description of a simple magnetometer is given, in which single-pass generation is realized on vapours of rubidium/cesium atoms located in an optical cell of several centimeters long, when resonant laser radiation with a wavelength of 852 nm (in the case of Cs) or 780 nm (in the case of Rb) passes. It is demonstrated that at the degenerate two-level cyclic transition Fe&gt;Fg, an inverse population is realized between the upper and lower Zeeman sublevels. The sensitivity (change) of the output power of the generated radiation with a change in the external magnetic field by ~70 nT is achieved. It is shown that the system can function as a metal detector, and an advantage over commercial metal detectors is noted. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>однопроходная генерация</kwd><kwd>магнитометр</kwd><kwd>инверсная населенность</kwd><kwd>атомы рубидия/цезия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>single-pass generation</kwd><kwd>magnetometer</kwd><kwd>population inversion</kwd><kwd>rubidium/cesium atoms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Комитета по высшему образованию и науке  Республики Армения в рамках проекта N 1-6/IPR.
