CESIUM FREQUENCY STANDARD FOR LASERS AT LAMBDA=1.06-MU-M

High-resolution spectra of the X1Σ+g−A1Σ+u band of molecular cesium at λ= 1.06 μm have been measured. An absolute wave-number reference table for lasers emitting at λ = 1.06 μm has been established. The cesium resonances are calibrated with respect to the well-known molecular-iodine absorption lines at λ = 0.53 μm. An accuracy of 10−7 has been achieved. © 1990 Optical Society of America.
