Paper Abstract

In this paper we propose two schemes for measuring the backscattering of ultra-smooth mirrors, the principle of which is discussed detailed. The difference between the two schemes is also disclosed. According to the more sophisticated scheme we have built a practical apparatus, which has the precision and high efficiency advantage. The details of the design are presented. According to the backscattering amplitudes obtained using the apparatus, ultra-smooth mirrors have been divided into four groups. The statistical data has shown that the lock-in thresholds of ring laser gyros are correlative with the backscattering amplitudes of mirrors. Therefore the validity of the measurement is demonstrated. The method and the apparatus presented here can help the ring laser gyro (RLG) manufacturers in reducing the lock-in thresholds of RLGs.
