FIELD: producing active elements with internal mirrors for stabilized dual-frequency gas lasers.
SUBSTANCE: optical assemblies are placed prior to and after annealing in magnetic field whose cross component is perpendicular to active element axis amounting to 0 < H ≤ 50 mT. Direction of magnetic-field induced cross component is determined and mark is applied. Assemblies are positioned until marks are aligned. Optical assemblies are soldered when marks are positioned on those corresponding to alignment between directions of cross components of magnetic field.
EFFECT: enhanced stability of laser radiation polarizing properties.
