The stabilization of a He-Ne (helium-neon) laser to hyperfine structure (HFS) components of the P(48)11-3 transition of (I-127)2 at 612 nm observed in an external iodine cell, may give a frequency reproducibility of + or - 5 kHz or + or - 1 x 10 to the -11th nu and a stability of 1.4 x 10 to the -13th nu for an observation time tau = 100 s. From He-3-Ne-22 lasers stabilized to HFS components of (I-127)2 observed in an intracavity cell, both at 612 and 640 nm wavelengths, a reproducibility of + or - 2 x 10 to the -10th nu can be expected. Common and convenient operating conditions have been found at both wavelengths. 12 references.
