Frequency combs are the robust and reliable backbone of cutting-edge experiments. This thought is guiding our frequency comb product development. It’s a shared vision with our customers, who want to focus more on the application and spend less time maintaining their system.

TOPTICA's DFC CORE+ was designed to combine the highest stability with reliability at the push of a button. With our award-winning CERO technology, we achieve ultra-low noise performance while reducing complexity: The light waveform itself is fixed from pulse to pulse by passively setting the carrier-envelope offset frequency fCEO to zero. No control loops, no electronic noise, and orders of magnitude faster noise suppression compared to conventional frequency combs.

With our complete frequency comb solutions, including seamless locking of all TOPTICA lasers, we don't deliver separate components but stable optical frequencies from the UV to the mid-IR. With that, even the most demanding applications like optical clock comparison and sub-Hz spectral purity transfer are enabled—reliable and easy to use.
