Эта модель представляет собой систему двух дифференциальных уравнений с запаздыванием. Время запаздывания предполагается достаточно большим. Для данной модели найдено условие существования непрерывных волн: параметры, задающие ” главную часть“ решения, должны лежать на некоторых кривых (Γ(κ, g0)). Найдены достаточные условия устойчивости непрерывных волн при всех достаточно больших значениях запаздывания. Изучено располо- жение областей устойчивости на кривых Γ(κ, g0). В случае нулевого фактора уширения спектральной линии лазера α для всех значений параметров коэффициента ослабления, описывающего линейные нерезонансные потери за обход резонатора, κ и параметра линейного ненасыщенного поглощения g0 аналитически найдены количество областей устойчивости и их границы на кривых Γ(κ, g0). Проведено сравнение результатов о расположении областей устойчивости на кривых Γ(κ, g0) для нулевого и ненулевого значений параметра α.</p></abstract><trans-abstract xml:lang="en"><p>The problem of existense and stability of continuous wave (CW) solutions R exp(iΛt) of a Fourier Domain Mode Locking laser model is studied. This model consists of two differential equations with delay. The delay is sufficiently large. It is nessesary for the existense of CW solutions of this model that parameters determining the ”main part” of solution must lie on a certain curve (Γ(κ, g0)). Sufficient conditions of stability of CW solutions for all sufficiently large values of delay are found. The location of stability regions on Γ(κ, g0) is studied. In the case of zero linewidth enhancement factor α for all values of parameters of the linear attenuation factor per cavity round trip κ and the linear unsaturated gain parameter g0 the number of stability regions and their boundaries on Γ(κ, g0) are found analytically. The comparison of location of stability regions on Γ(κ, g0) in tha case of zero α and nonzero α is made.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>FDML лазер</kwd><kwd>малый параметр</kwd><kwd>большое запаздывание</kwd><kwd>устойчивость</kwd><kwd>непрерывная волна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FDML laser</kwd><kwd>small parameter</kwd><kwd>large delay</kwd><kwd>stability</kwd><kwd>continuous wave</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">базовая часть государственного задания на НИР ЯрГУ</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Slepneva S., Kelleher B., O’Shaughnessy B., Hegarty S.P., Vladimirov A.G., and Huyet G.
