Data
The rack-mounted ORS of the FC1500-Quantum is characterized in terms of single-sideband optical phase noise power spectral density and fractional frequency stability. Menlo Systems carries on detailed analysis for each system to guarantee ultimate performance and uninterrupted operation. A three-cornered hat technique is used to provide absolute noise analysis of the ORS.
The ultra-low-noise frequency comb is qualified against a reference system. The Spectral Purity Transfer performance is analyzed for short-term phase noise performance and long-term fractional frequency stability, to ensure negligible additive noise. Here, the residual phase noise of an ECDL at 698 nm in the FC1500-Quantum is measured against a reference system, proving the exquisite transfer of phase-coherence from the optical reference system to the high Q-factor clock transition in neutral Strontium.
We believe in fully phase-locked systems, being the only path for phase-coherently transfer the purity from one specific optical frequency to all frequencies. Here the robustness of our phase-lock-loops is measured, demonstrating the negligible additive noise and the full control of the disciplined CW lasers.
