Influence of He-Ne Pressure on Biasing Value of Zeeman Laser Gyroscope

Biasing effect of Zeeman laser gyroscope affected by the pressure has been studied theoretically and experimentally.It is found through the theoretical analysis that the pressure of He-Ne gas will considerably affect biasing value of the gyroscope,which indicates that the value linearly depends on the pressure of the gas with the ratio unchanged.The relationship between the biasing value and the intensity of pressure with typical parameters was then theoretically presented.Biasing value was further measured with different pressure.The comparison between the theoretical result with the measurement shows good agreement and hence verifies the validity of the theoretical model;the biasing value correlation to intensity of pressure has been showed.The research will provide theoretical basis for choosing the intensity of pressure of He-Ne gas,which is of practically importance for Zeeman laser gyroscope design consideration.
