Abstract

Subject of study. In this study, methods for evaluating the engineering design and energy characteristics of a novel laser system comprising volumetric cylindrical and spherical shells (layered solid-state lasers) are investigated. Aim of study. The aim is to develop a model for evaluating the characteristics of a layered solid-state laser containing active media in various aggregate states. Method. The well-known Gaussian beam model is used to describe the field structure of the light beam formed in the resonator and to determine the aperture of the mirrors of the generating laser module. To examine the output characteristics of the layered laser module, a classical system of balanced equations for a four-level active medium is used. Main results. A novel approach for constructing laser systems is proposed; it involves volumetric cylindrical and spherical shells partitioned by laser modules with adjacent lateral surfaces. Calculations for the resonator-optical and laser-dynamic characteristics of the layered laser module are performed. The obtained results include values for the geometric characteristics of the resonator and optical elements of the module, as well as the peak power values for generation and pumping pulses in cases where the pumping sources are filled with nitrogen or argon. Practical significance. The initial number and thickness of layers can be adjusted in the developed mathematical model to enable the evaluation of both the structure of the light beam in the resonator and the generation characteristics of the gas and solid-state modules separately and combined (in the case of alternating solid layers of the active medium and gas layers of the pumping sources).
