Abstract The noise characteristic of available laser sources limits the sensitivity of saturated absorption spectroscopy. Time averaging is one method to improve the signal-to-noise ratio. A computer controlled dye-laser spectrometer is described which has the capability to scan several times any selected frequency range with an absolute accuracy of ±200 kHz. The sensitivity of this system is demonstrated by measuring the isotope shift of the low abundant38Ar and by detecting a weak83Kr-hyperfine component.
