We demonstrate a time scale based on a phase stable optical carrier that accumulates an estimated time error of $48\pm94$ ps over 34 days of operation. This all-optical time scale is formed with a cryogenic silicon cavity exhibiting improved long-ter

Mechanical loss of dielectric mirror coatings sets fundamental limits for both gravitational wave detectors and cavity-stabilized optical local oscillators for atomic clocks. Two approaches are used to determine the mechanical loss: ringdown measurem

We investigate the spectral purity transfer of highly stable lasers from 194 THz to 429 THz using optical frequency combs. In a first measurement, the purity transfer through two identical ultra-low-noise frequency combs is assessed. In a second meas

We present the thermal noise limited performance of a cryogenic ultrastable silicon optical cavity operated at 4 K. A three-cornered comparison with two other ultrastable resonantors shows that the 4 K system is largely limited by a flicker frequency

We report on a laser locked to a silicon cavity operating continuously at 4 K with $1 \times 10^{-16}$ instability and a median linewidth of 17 mHz at 1542 nm. This is a ten-fold improvement in short-term instability, and a $10^4$ improvement in line

We report on two ultrastable lasers each stabilized to independent silicon Fabry-Perot cavities operated at 124 K. The fractional frequency instability of each laser is completely determined by the fundamental thermal Brownian noise of the mirror coa

Stable and spectrally narrow laser sources referenced to ultrastable passive Fabry-Perot cavities are invaluable for optical atomic clocks and they find important applications, e.g. in precision tests of relativity or novel radar applications. Ultima

Conference on Lasers and Electro-Optics.
We report on two ultrastable lasers stabilized to single-crystal silicon Fabry-Perot cavities at 124 K. The lasers show unprecedented thermal noise-limited frequency instabilities of 4×10−17 and linewidths below 10 mHz.

Crystalline optical cavities are the foundation of today’s state-of-the-art ultrastable lasers. Building on our previous silicon cavity effort, we now achieve the fundamental thermal-noise-limited stability for a 6 cm long silicon cavity cooled to
