Проведено численное моделирование режима регулярных пульсаций, возникающего в условиях нелинейного смещения и уширения резонансной линии усиления из-за влияния ближних полей диполей и поглощения в квазирезонансных переходах на диэлектрическую восприимчивость активной среды. Моделирование проведено для параметров полупроводниковых квантоворазмерных структур.</p></abstract><trans-abstract xml:lang="en"><p>The results of a qualitative analysis of a semiclassical model of light generation in low-dimensional solidstate lasers, including quantum-dot microlasers and, on its basis, a numerical modelling of the regular pulsation regime that occurs under conditions of nonlinear shift and broadening of the resonant spectral gain line due to the influence of dipoledipoles interaction and absorption in quasi-resonant transitions on the dielectric susceptibility of the active medium are herein presented. The modelling of lasing was carried out for the parameters of semiconductor quantum-dot structures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазеры пониженной размерности</kwd><kwd>суперкристаллы квантовых точек</kwd><kwd>резонансная оптическая нелинейность</kwd><kwd>самоподдерживающиеся пульсации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-dimensional lasers</kwd><kwd>quantum dot supercrystals</kwd><kwd>resonant optical nonlinearity</kwd><kwd>self-sustaining pulsations</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">Quantum-dot supercrystals for future nanophotonics / A.
