Description: Simplified diagram of Braxmaier et al.'s 2002 repeat of the Kennedy-Thorndike experiment. On the left, photodetectors (PD) monitor the resonance of a sapphire cryogenic optical resonator (CORE) length standard kept at liquid helium temperature to stabilize the frequency of a Nd:YAG laser to 1064 nm. On the right, the 532 nm absorbance line of a low pressure iodine reference is used as a time standard to stabilize the (doubled) frequency of a second Nd:YAG laser.
