Установлены токовые зависимости мощности и спектров излучения светодиодов сине-зеленого диапазона в их взаимосвязи с эффективностью накачки титансапфировой активной среды. Оценены достижимые плотности мощности оптической накачки при использовании светодиодов.</p></abstract><trans-abstract xml:lang="en"><p>The electroluminescent characteristics of powerful AlInGaN LEDs in the regime of high-pulsed current are investigated. The current dependencies of power and emission spectra of blue-green LEDs are established in their relationship with the efficiency of active medium Ti:Sapphire pumping.
