Abstract :
A method of CO laser frequency stability measurement is proposed, based on the molecular laser magnetic resonance (LMR) spectrum, which can be used to measure the linewidths of molecular LMR spectra and their changes. The data were treated by the Allan variance method. A series of CO laser frequency stability measurements were obtained from 0.1 s to 1000 s in the time domain. The frequency stability was fitted to a power law function. The expressions of frequency stability were found for a stabilized and a free-running CO laser in the frequency domain.
