dc.description.abstractA new design of a laser resonator with smooth adjustment of radiation output is presented. Adjustment can be performed over a wide range and directly during laser operation. This provides optimal feedback under various laser operating conditions. The active element has an annular sectional shape. The pumping and cooling elements can be placed on the outer and inner sides of the active element. This ensures a uniform distribution of pump energy and good heat dissipation from the active substance. Gaseous, liquid and solid substances can be used as an active medium. The possibility of obtaining optimal feedback and homogeneity of the active substance make it possible to increase the efficiency of laser generation. Coaxially arranged conical mirrors provide a rational change in the radiation path in the cavity. The radiation makes a complete passage through the cavity in four different ways. This allows to minimize the effect of inhomogeneities of the active substance on the radiation, which improves the spatial-angular and energy characteristics of the output laser radiation. Conical 90° mirrors that are used in the laser cavity do not require careful alignment and provide increased laser stability. Such a resonator scheme is suitable for use in a wide frequency range, including the terahertz range.
