“…7͒ is wrapped directly around the laser tube. Such heaters have been used by a number of authors for the same purpose, [8][9][10] and more exotic means of temperature control have been used as well. 2,11, 12 We note in passing that we experimented with Peltier coolers, and found that they were much more difficult to control in a stable manner.…”

Instrum. 74, 3155 (2003);We describe a laser system for very-high-accuracy dimensional metrology. A sealed-cavity heliumneon laser is offset locked to an iodine-stabilized laser in order to realize a secondary standard with higher power and less phase noise. Synchronous averaging is employed to remove the effect of the frequency modulation present on the iodine-stabilized laser. Additional lasers are offset locked to the secondary standard for use in interferometry. All servo loops are implemented digitally. The offset-locked lasers have intrinsic linewidths of the order of 2.5 kHz and exhibit a rms deviation from the iodine-stabilized laser below 18 kHz. The amplitude noise is at the shot-noise limit for frequencies above 700 kHz. We describe and evaluate the system in detail, and include a discussion of the noise associated with various types of power supplies.
