Abstract:

The total reflection prism laser gyro is based on the principle of heating gas in the cavity to control the cavity length.The modeling software PROE is used in this paper to establish the analytical models,and finite element analysis software Ansys to analyze the “model jump” process,by which the factors are summarized that influence the stable single mode operation of the total reflection prism laser gyro.Methods for reducing the jumpmode time and improving the heating efficiency are proposed.
