A microrod optical-frequency reference in the ambient environment

28 Feb 2019 Zhang Wei Baynes Fred Diddams Scott A. Papp Scott B.

We present an ultrahigh-$Q$, solid-silica microrod resonator operated under ambient conditions that supports laser-fractional-frequency stabilization to the thermal-noise limit of $3 \times 10^{-13}$ and a linewidth of 62 Hz. We characterize the technical-noise mechanisms for laser stabilization, which contribute significantly less than thermal noise... (read more)
