Type of article: Article

Summary

A 1.6 KG SILICON MONOCRYSTAL WAS USED TO MAKE A FABRY-PEROT OPTICAL CAVITY OPERATED AT CRYOGENIC TEMPERATURES.HIGH-RESOLUTION THERMAL EXPANSION MEASUREMENTS WERE MADE AS THE SILICON COOLED TO 4.2 K IN ORDER TO CHARACTERIZE THE CAVITY AS A LENGTH REFERENCE STANDARD. A HELIUM-NEON LASER WAS THEN LOCKED TO A TRANSMISSION RESONANCE AT LIQUID-HELIUM TEMPERATURES, AND THE LASER FREQUENCY TRACKED THE CAVITY RESONANCE WITH ESTIMATED ERROR FLUCTUATIONS IN THE BANDWIDTH DIRECT CURRENT TO 1 HERTZ. IMPLICATIONS OF THE COMBINED SET OF DATA, THERMAL EXPANSION PLUS FREQUENCY-TRACKING FLUCTUATIONS, FOR USING SUCH A SYSTEM AS A FREQUENCY STANDARD ARE DISCUSSED.
