Abstract :
The mechanical construction of the stabilized lasers, and their electronic control equipment, are described. A free-running stability of 10-10 for 0.1 s and a servo-locked stability of better than 10-12 for 10 s counting time has been measured. Hyperfine structure intervals in both 127I2 and 129I2 with standard deviation of 12 kHz confirm earlier values.
