Abstract

Abstract: Owing to the uncontinuously tunable property of CO laser, the frequency stability is very difficult to be determined by using direct molecular absorption spectrum. A new measurement method of laser frequency stability is proposed in this paper. The method is based on molecular spectrum of laser magnetic resonance (LMR). The variation of linewidth of molecular LMR spectrum were treated by Allan variance method. A series of CO laser frequency stabilities were obtained from 0.1s to 1000s. The frequency stabalities were fitted by power function in a computer. The expressions of frequency stabilities are found for stabilizing and free-running CO laser.

Key words: Laser frequency stability, Laser magnetic resonance, CO laser
