Abstract. The problems of synthesis of stable resonators of solid-state lasers used for Hermite — Gaussian beams generation are discussed. Formulas describing relation of laser beam parameters at the input and output of the active element with parabolic profile of reflective index are derived. A method is developed for synthesis of solid-state laser resonator; the method is reported to ensures the generated beam spatial parameters matching characteristics of thermo-optically distorted active element. Results of resonator synthesis for solid-state laser are presented.
Keywords: solid-state laser, resonator, stable resonator, active element, gradient medium, thermal lens, Hermite — Gaussian beam, synthesis of resonator
