Abstract
We use the three-cornered-hat method to evaluate the absolute frequency stabilities of three different ultrastable reference cavities, one of which has a vibration-insensitive design that does not even require vibration isolation. An Nd:YAG laser and a diode laser are implemented as light sources. We observe Hz beat note linewidths between all three cavities. The measurement demonstrates that the vibration-insensitive cavity has a good frequency stability over the entire measurement time from 100 s to 200 s. An absolute, correlation-removed Allan deviation of at 1 s of this cavity is obtained, giving a frequency uncertainty of only 0.44 Hz.
