Проведена регистрация временных изменений интенсивности спектральных линий меди, цинка, олова и свинца при двухимпульсной лазерной абляции образцов чистых металлов и многокомпонентных сплавов. Определено, что для чистых металлов временныe зависимости интенсивности спектральных линий могут быть с высокой точностью аппроксимированы экспоненциальными зависимостями, при абляции же многокомпонентных образцов экспоненциальное затухание аналитического сигнала имело место лишь при межимпульсных лазерных интервалах &lt;3 мкс.</p></abstract><trans-abstract xml:lang="en"><p>A spectral-kinetic recorder operating in a special time-gating mode has been developed for time-shifted measurement of time-resolved spectra and the kinetics of the spectral line emission in atomic emission analysis. The luminescence kinetics of copper, zinc, tin, and lead spectral lines were recorded in the case of two-pulse laser ablation of samples of pure metals and multicomponent alloys. It was determined that the luminescence kinetics of spectral lines can be approximated by exponential dependences with high accuracy for pure metals, while for multicomponent samples, the exponential decay of the analytical signal occured only at interpulse laser intervals &lt;3 μs. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерная абляция</kwd><kwd>сдвоенные лазерные импульсы</kwd><kwd>временные зависимости интенсивности</kwd><kwd>лазерная плазма</kwd><kwd>лазерная атомно-эмиссионная спектроскопия</kwd><kwd>laser ablation</kwd><kwd>double laser pulses</kwd><kwd>intensity kinetics</kwd><kwd>laser plasma</kwd><kwd>laser induced breakdown 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">Ph.
