Abstract: Изобретение относится к лазерной технике. Способ нелинейного внутрирезонаторного преобразования длины волны в лазере с продольной накачкой заключается в том, что для генерации на основной оптической частоте в лазере используют резонатор, конфигурация которого обеспечивает возможность одновременной генерации нескольких поперечных мод, вырожденных по фазовым набегам; располагают в непосредственной близости к одному из зеркал 1, 2 твердотельный активный элемент 3; размещают в резонаторе нелинейный элемент 4; фокусируют пучок 7 излучения оптической накачки в твердотельный активный элемент 3 вдоль оси резонатора. Пучок 7 излучения оптической накачки в твердотельном активном элементе 3 имеет диаметр меньше, чем диаметр гауссовой моды резонатора, в результате чего генерация на основной оптической частоте происходит на суперпозиции поперечных мод с образованием области повышенной интенсивности излучения, при этом нелинейный элемент 4 размещают в области повышенной интенсивности излучения. Технический результат заключается в обеспечении возможности повышения внутрирезонаторного нелинейного преобразования без использования дополнительных зеркал резонатора. 2 з.п. ф-лы, 6 ил.
