Abstract :
Results of absolute frequency calibration of the He-Ne/CH/sub 4/ transportable optical frequency standard (TOFS) and intercomparisons of the TOFS with CO/sub 2//OsO/sub 4/ OFS carried out on 1996-1997 by a collaboration of three organizations (Lebedev Institute, PTB, and BNM-LPTF) are reported.
