Abstract

We demonstrate a method to measure and actively reduce the coupling of vibrations to the phase noise of a cavity-stabilized laser. This method uses the vibration noise of the laboratory environment rather than active drive to perturb the optical cavity. The laser phase noise is measured via a beat note with a second unperturbed ultra-stable laser while the vibrations are measured by accelerometers positioned around the cavity. A Wiener filter algorithm extracts the frequency and direction dependence of the cavity response function. Once the cavity response function is known, real-time noise cancellation can be implemented by use of the accelerometer measurements to predict and then cancel the laser phase fluctuations. We present real-time noise cancellation that results in a 25 dB reduction of the laser phase noise power spectral density.

The setup used to measure the cavity response functions and perform real-time noise cancellation. Six accelerometers (labeled 1-6) are positioned on the table such that (1,3,5) measure accelerations in the vertical (z) direction while (2,4,6) measure accelerations in the horizontal (x,y) plane. This combination of signals allows the measurement of all six motional degrees of freedom. The test light is transmitted to the frequency comb through a noise-cancelled optical fiber [14,15], and the heterodyne beat note (mixed to approximately 4 MHz) measured at the frequency comb returns through a coaxial cable.

Fig. 2.
Fig. 2.

(a) The time domain performance of the Wiener filter algorithm. The measured laser phase (blue), predicted phase (green) and residual error (black) show that the Wiener filter reduces the RMS phase fluctuations by more than an order of magnitude. The inset on the lower left shows the first 0.5 seconds of the time trace. Here, the error is initially large due to the lack of accelerometer information for times t < 0 s. By t = 0.2 s there is a sufficient history of accelerometer measurements to substantially reduce the phase error. The inset on the lower right shows the Wiener filter suppressing the RMS phase fluctuations of the laser by more than a factor of 10. (b) The phase noise power spectral density (PSD) of the measured phase, predicted phase and residual phase error showing more than 30 dB of noise cancellation at 12 Hz. The dashed traces show the velocity PSD measured by the accelerometers.

Fig. 3.
Fig. 3.

(a) The fractional sensitivity of the cavity reference frequency to accelerations for the three translational (x,y,z) degrees of freedom in the 5–30 Hz spectral region. Three independent measurements were performed for each direction (markers) and the solid lines show the average values. (b) The measured SNR of the phase and acceleration measurements show that outside of the 5–30 Hz region, there is insufficient SNR to calculate the cavity acceleration sensitivity.

(a) The laser phase PSD for three operating conditions: (1) the cavity table resting on the floor with the filter turned off (blue), (2) the cavity table resting on the floor with the filter turned on (green), and (3) the cavity table suspended by vibration isolating rubber bands (black). A real-time noise cancellation of 25 dB is achieved at 12 Hz compared to the free running case, but still several dB more than the vibration isolated case. The direction-averaged velocity PSD shows the effect of the rubber band suspension system in isolating the cavity from laboratory vibration noise. (b) The Allan deviation for the test laser in the three cases shown in (a). Without the LMS filter, the laser frequency instability increases by more than an order of magnitude at τ = 0.1 s and by a factor of 4 at τ = 1 s compared to the vibration isolated case (black). When the LMS filter is on, the test laser instability is within a factor of 2 compared to the vibration-isolated case for all time-scales. The points above and below each Allan deviation curve show the 90% confidence interval for the measurement.
