This, and part II following, describe a determination of the speed of light made by measuring the frequency and wavelength of radiation from a CO 2 laser. This laser was operated on the 9.3 μm R(12) transition, and stabilized by reference to fluorescence in an external CO 2 absorption cell. The laser frequency was measured via a sequence of harmonic-mixing stages involving the HCN and H 2 O lasers as transfer oscillators, and was found to be 32 176 079 482 ± 14 kHz ( ± 4.2 parts in 10 10 ). A correction to this value of — 10 kHz is necessary to obtain the centre frequency of the CO 2 reference transition. The wavelength measurements and value of c are described in part II.

The Mathematical Model

The system based on the working principle of MAX1978 and TEC, using multi-point at different frequency measurement method, and establishing corresponding mathematical model. Confirmed the pole-zero plot of the PID, according to the amplitude-frequency and phase-frequency characteristics of the mathematical model, and then, adjusted the corresponding resistance and capacitance of the circuit to make the accuracy of the temperature adjustment to 1E-3centigrade.
