    Progress with a Determination of the Speed of Light

    The scheme for measuring the CO2 laser frequency (shown in the Introduction) consists of three separate frequency-mixing experiments using two lower-frequency lasers as transfer oscillators. If an accurate measur...

    Progress with a Determination of the Speed of Light

    Until recently the direct measurement of frequencies in the infra-red spectral region has not been possible because of the lack of suitable detectors and mixers with response times of the order of 10−13 to 10−14 ...
