Abstract

We have stabilized two 1064 nm Nd:YAG lasers to two independent Fabry-Perot interferometers. The interferometers are housed separate vacuum vessels and independently temperature stabilized. The ultra-low loss mirrors provide cavity finesses of about 200,000 and cavity linewidths of 5 kHz. The servo control systems use the reflected PM discriminator. Fast feedback to control the laser frequency is applied to a piezoelectric transducer, whereas slow control is made possible by temperature-tuning of the laser crystal. Allan variance measurements of the beatnote between the two laser systems are less than 3 X 10^-14 for delay times between 0.1 and 1 s.
