Лазерное генераторно-усилительное устройство одномодового излучения для термической обработки материалов позволяет увеличить плотность мощности излучения в зоне лазерного воздействия и повысить ресурс работы устройства. Это достигается тем, что устройство снабжено по крайней мере одним дополнительным усилителем, светоделителем и оптической системой, при этом усилители соединены параллельно, излучение генератора делится светоделителями и направлено на входы усилителей, излучение усилителей направлено в одну точку, расположенную в фокусе оптической системы, а угол схождения лучей удовлетворяет условию
tgφ ≤ (D-d)/F,
где φ - угол схождения лучей;D - диаметр апертурной диафрагмы оптической системы; d - диаметр луча парцального усилителя в месте расположения апертурной диафрагмы;F - фокусное расстояние оптической системы.Laser generator-amplifier device of single-mode radiation for heat treatment of materials allows to increase the power density of the radiation in the area of laser exposure and increase the service life of the device. This is achieved in that the device is equipped with at least one additional amplifier, a beam splitter and an optical system, while the amplifiers are connected in parallel, the generator's radiation is divided by beam splitters and directed to the inputs of the amplifiers, the radiation of the amplifiers is directed to one point located in the focus of the optical system, and convergence of the rays satisfies the condition
tgφ ≤ (Dd) / F,
where φ is the angle of convergence of the rays; D is the diameter of the aperture diaphragm of the optical system; d is the diameter of the beam of the partial amplifier at the location of the aperture stop; F is the focal length of the optical system.
