Abstract
A ring laser gyro is shown having a mirror designed for maximum reflectivity of parallel and perpendicularly polarized light at a frequency slightly greater or less than the frequency of the laser. In this configuration, the reflection of the preferred perpendicularly polarized light is reduced but slightly, while the reflection of the less desirable parallel polarized light is reduced significantly.
