This is proof of the exceptional coherence of all comb lines of the RF-locked DFC CORE +. Moreover, it shows that the origin of the DFG comb is truly at 0 Hz, anything acting on the DFC CORE + acts

100 times faster noise reduction

The passive all optical fCEO stabilization has distinct advantages with respect to the conventional f-to-2f-interferometer approach. This has been pointed out by several major players in the field

CERO - How it works

URL: /technology/toptica-proprietary/cero-1#c22588

How it works The operating principle of the offset-free Difference Frequency Comb (DFC) relies on generating a broadband supercontinuum from the output of a low noise Er-fiber mode-locked oscillator

CERO technology – zero fCEO Our awarded CERO technology enables an inherently fCEO-stable frequency comb design that combines robustness with reliability and highest stability. The offset frequency

CERO - Perfect lock to optical reference

URL: /technology/toptica-proprietary/cero-1#c22662

Perfect lock to optical reference By fixing fCEO to zero with the DFG process we achieve exceptionally low noise at the frequency origin and completely decouple fCEO and frep. This is particularly

CERO - Ultra-low noise and narrow linewidth

URL: /technology/toptica-proprietary/cero-1#c22663

Ultra-low noise and narrow linewidth The CERO technology uses a passive, all-optical phase-lock for stabilizing the offset frequency fCEO. By that our comb system requires one electronic locking

CERO - 100 times faster noise reduction
