Measurement of sub-fm/Hz1/2 displacement spectral densities in ultrahigh-Q single-crystal microcavities with hertz-level lasers
文献摘要：
Tracing a resonance frequency of a high quality factor(Q)optical cavity facilitates subpicometer displacement measurements of the optical cavity via Pound-Drever-Hall(PDH)locking scheme,tightly synchronizing a laser frequency to the optical cavity.Here we present observations of subfemtometer displacements on a ultrahigh-Q single-crystal MgF2 whispering-gallery-mode microcavity by frequency synchronization between a 1 Hz cavity-stabilized laser and a resonance of the MgF2 cavity using PDH laser-cavity locking.We characterize not only the displacement spectral density of the microcavity with a sensitivity of 1.5×10-16 m/Hz1/2 over the Fourier offset frequency ranging from 15 mHz to 100 kHz but also a 1.77 nm displacement fluctuation of the microcavity over 4500 s.Such measurement capability not only supports the analysis of integrated thermodynamical and technical cavity noise but allows for minute displacement measurements using laser-cavity locking for ultraprecise positioning,metrology,and sensing.
