Aerospace Instrument-Making Annotation << Back Modelling the processes of degrading in the discharge of helium-neon ring laser A. V. Molchanov, V.M. Suminov, M, V. Cltirkin Wide application of laser gyroscopes as sensor of angular position in strapdown inertial navigating systems creates necessity for reliable methods of individual forecasting service life of these devices. The principal cause limiting a resource of the helium-neon laser with excitation of the active environment by discharge of the direct current consists of gradual reduction of neon quantity in a gas mix. Questions of development of the mathematical model, permissive the choice of rating values and their maximum deviations and the allocation of the gas discharge characteristics connected to resource ring laser are solved rationally.
