Laser gyros are almost as well-known for their disabilities as for their performance capabilities. Of all their disabilities, however, the most prominent and perhaps the most fundamental defect of laser gyro operation is the lock-in phenomenon. This paper shows polarization can play a key role in circumventing the lock-in deficiencies of laser gyroscopes. Preliminary analysis in fact suggests that rotation rates down to 10 to the minus 8th power or 10 to the minus 9th power radians per second may be detectable by either system. This lends some hope to the possibility that accuracy goals may eventually be met.
