Abstract:

New measurements of CO2 laser wavelengths in the 9 micrometer and 10 micrometer bands are reported accurate to about 2X10 to the minus 8th power. These are used in combination with Evensons recently reported frequency values to derive a new value for the velocity of light and to update Changs CO2 frequency and wavelength tables. Author
