“…A portable He-Ne laser from BIPM, BIPM-P3, also participated in the intercomparison and its frequency was measured relative to both JILA-145 and INMS-3. The frequency difference between BIPM-P3 and BIPM-4, which serves as the representative value for a practical realization of the definition of the meter [12], was measured at BIPM before and after this intercomparison. Hence the frequency of the transfer oscillator, JILA-145, is now connected to the BIPM standard, as well as to both chains in NRC and JILA.…”

Using an iodine-stabilized He-Ne laser as a transfer oscillator, we compare absolute measurements of the optical frequency from a traditional frequency synthesis chain based on harmonic generation and from the frequency division technique of an ultrawide bandwidth femtosecond frequency comb. The agreement between these two measurements, both linked to the Cs standard, is 220+/-770 Hz, yielding a measurement accuracy of 1.6x10(-12). We report 473 612 353 604.8+/-1.2 kHz as a preliminary updated value of the absolute frequency of the " f" component for the He-Ne laser international standard at 633 nm.

We present an improved technique for detection of trace impurities in iodine-filled absorption cells for laser frequency stabilization. The results of purity investigation are compared to frequency shifts measured with a set of two iodine stabilized Nd:YAG lasers. The setup for direct fluorescence measurement with an Argon-ion laser operating at 502 nm wavelength is equipped with compensation for laser power and spectral instabilities.
