Abstract

Frequency measurements of 16 lines of I2 in the near infrared have been performed using different Rb frequency references: diode lasers stabilised to the Rb D1 line at 377 THz, to the Rb D2 line at 384 THz and to the 5 s -5 d two photon transition at 385 THz. The relative uncertainties of the measurements of are limited by the frequency stability of the laser source locked to I2 in the case of the Rb D2 and two photon transition or by the accuracy of the Rb D1 line. The internal consistency of calibrations of iodine lines is shown to be better than by measurements of the difference frequencies of calibrated iodine lines using four-wave mixing in laser diodes.
