Paper Abstract

The technology of the laser gyro has advanced to where production of this unique gyro with low cost and high performance is now possible. The technology of lifetime and its factors have now shown operating lifetime capability in excess of 50,000 hours. The performance variation with wavelength and size shows the wide range of parameters which must be considered. The performance of the laser gyro in scale factor linearity varies from 0.1% in the small 9.8 cm 1.15μ gyro to better than 0.0001% in the 43 cm 0.63μ gyro. In similar fashion the null stability and performance also varies over a range of 10°/hr to 0.01°/hr for the same gyros, respectively. Other factors such as gas pressure and multi-mode effects are also discussed.
