Abstract
Mirrors are tested separately at different distances to plasma in separate ring laser gyros. Testing mirrors a predetermined distance away from plasma in the gyros allows accelerated testing of the environment of the mirrors in gyros. The test results are graphed to also allow prediction of ring laser gyro life.
