Absolute Frequency Measurement of the R(12) Transition of CO2 at 9.3 µm

Nature volume 244, page 504 (1973)Cite this article

Abstract

THE frequency of a CO2 laser stabilized to the R(12) transition of CO2 has been measured with an accuracy better than one part in 109. This is part of an experiment at the National Physical Laboratory to determine the speed of light to the full accuracy of the krypton-86 length standard1.
