R-r=zc/2;
zt=2a2/λ;
где zc - расстояние Тальбо для цилиндрической системы, zt - расстояние Тальбо для плоского случая, r - радиус зеркала связи, R - радиус окружности, на которой находятся апертуры лазеров, - период набора по дуге окружности, φo - угол между осями соседних лазеров, λ - длина волны генерации.The invention relates to laser technology, in particular to multichannel lasers with a new form of optical resonator, specifically cylindrical. The proposed multi-channel coherent source can be used to create systems of laser technology, laser controlled thermonuclear fusion. The aim of the invention is to develop a compact device that provides common-mode radiation of a circular set of lasers and, consequently, obtaining a high power density with minimal diffraction losses in a common resonator. The essence of the invention is that the lasers are periodically arranged in an arc of a circle around a translucent coupling mirror, which is a circular cylinder perpendicular to the plane of the circle. In this case, the laser radiation is directed to the center of this circle, which lies on the axis of the mirror. As a result, lasers are located in a cylindrical Talbot resonator, in which full reproduction takes place along the angular coordinate of the periodic structure of the field of a set of lasers. Thus, optical coupling between the lasers of the array is carried out, the threshold of their in-phase generation reaches a minimum, and in the vicinity of the axis of the translucent coupling mirror there occurs a coherent addition of radiation converging from circumferentially located lasers. The parameters of the Talbot cylindrical resonator are calculated in accordance with the following formulas, obtained on the basis of the theory of diffraction from the condition of full reproduction of the periodic field of a set of lasers:
Rr = z c / 2;
z t = 2a 2 / λ;
where z c is the Talbot distance for the cylindrical system, z t is the Talbot distance for the plane case, r is the radius of the coupling mirror, R is the radius of the circle where the laser apertures are located, - the period of collection along the arc of a circle, φ o - the angle between the axes of neighboring lasers, λ - the wavelength of generation.
