Abstract :
The reflected light intensity from an extremely low thermal coefficient of zerodur etalon was utilized to stabilize laser frequency using Pound-Drever-Hall approach. The reflective signal-to-noise ratio of etalon is affected by coated mirror reflectivity and insertion loss. Over 6 dB signal-to-noise ratio and more than 100 etalon finesse were demonstrated.
