Abstract
A simple stabilizer for locking 543 nm, 612 nm and 633 nm helium-neon lasers to iodine is described. When applied to a 543 nm laser, a long term frequency stability of 1.4 X 10-12 was observed. One stabilizer can lock three lasers simultaneously to iodine references with relative uncertainties better than 2 X 10-10 for sample times greater than 1 s, providing primary frequency references that can be used for gauge block measurements.
