The absolute frequency of the 473-THz He--Ne laser (633 nm), stabilized on the g or i hyperfine component of the /sup 127/I/sub 2/ 11--5 R(127) transition, was measured by comparing its frequency with a known frequency synthesized by summing the radiation from three lasers in a He--Ne plasma. The three lasers were (1) the 88-THz CH/sub 4/-stabilized He--Ne laser (3.39 ..mu..m), (2) a 125-THz color-center laser (2.39 ..mu..m) with its frequency referenced to the R/sub II/(26) /sup 13/C/sup 18/O/sub 2/ laser, and (3) the 260-THz He--Ne laser (1.15 ..mu..m) referenced to an I/sub 2/-stabilized dye laser at 520 THz (576 nm). The measured frequencies are 473 612 340.492 and 473 612 214.789 MHz for the g and i hyperfine components, respectively, with a total uncertainty of 1.6 parts in 10/sup 10/. The frequency of the i component adjusted to the operating conditions recommended by the Bureau International des Poids et Mesures is 473 612 214.830 +- 0.074 MHz.
