Abstract

The single-frequency cw YAG:Nd laser with frequency stabilization onto spectroscopic standard at 1.06 μm - molecular cesium absorption lines - is described. It is shown, that the spectrum of saturated absorption of Cs₂ gives for this spectral range the optical scale of reference frequencies, which is convenient for the utilization in interferometric systems and in the heterodyne systems in particular. Spectroscopic properties of this cesium reference are presented. The heterodyne measurements of Allan variance in the experiments with two independent frequency stabilized YAG:Nd lasers which gave the highest value of relative frequency stability at a level of 6x10^-11 are described.
