摘要：
This paper presents complex method and the description of the setup based on it that allows to control different parameters of ring laser cavities for gyro sensors during the technological process of manufacturing. First of all this is accuracy of monoblock cavity manufacturing, accuracy of mirror alignment, the level of cavity selection, the control of sphericity of cavity, measurement of diffraction cavity losses, back scattering and the active substance gain in the cavity. Complex method combines the analysis of cavity transmission spectrum, measurement of the resonance transmission peak and measurement of radiation decay time in the cavity. The analysis of the influence of cavity characteristics on the accuracy of laser gyros is carried on.
