Изобретение относится к технической физике, в частности к устройствам для усиления лазерного излучения. Известные волоконные световоды оптического квантового усилителя не обеспечивают в малосигнальном режиме высокую среднюю интенсивность выходного излучения или позволяют ее увеличить, но только при одновременном увеличении пороговой мощности накачки, когда волоконный световод легирован ионами редкоземельных элементов, работающих по трехуровневой схеме. Устройство дает возможность увеличения средней интенсивности выходного сигнального излучения, насыщающего волоконно-оптический квантовый усилитель, без увеличения пороговой мощности накачки, когда усилитель выполнен на основе волоконного световода, легированного ионами редкоземельных элементов, работающих по трехуровневой схеме. Устройство выполнено в виде волоконного световода, состоящего из сердцевины, световедущей области и окружающей их оболочки. Световедущая область легирована ионами редкоземельных элементов, причем расстояние от оси сердцевины до ближайшей точки световедущей области удовлетворяет определенному соотношению.The invention relates to the technical physics, in particular to devices for amplifying laser radiation. Known optical fibers of an optical quantum amplifier do not provide a high average output intensity in the small signal mode or allow it to be increased, but only with a simultaneous increase in the threshold pump power when the fiber light guide is doped with rare-earth ions operating in a three-level scheme. The device makes it possible to increase the average intensity of the output signal radiation, which saturates a fiber-optic quantum amplifier, without increasing the threshold pump power when the amplifier is made on the basis of a fiber light guide doped with rare-earth ions working in a three-level scheme. The device is made in the form of an optical fiber consisting of a core, a light-guiding area and the surrounding shell. The light-guiding region is doped with ions of rare-earth elements, and the distance from the core axis to the nearest point of the light-guiding region satisfies a certain ratio.
