Paper Abstract

This paper describes a coherent CO2 laser system. The master laser is stabilized over its tuning range by NH2D Stark cell and the local laser is offset frequency-locked by an electric loop. Error signal produced by NH2D Stark cell is analyzed and the phase fluctuation of the heterodyne signal due to noises is discussed. A 23Hz Allan variance for the beating signal between laser beams has been achieved at 1 s gate time.
