frequency combs

TOPTICA’s frequency comb product line is a modular system that supports a broad variety of applications. Three basic versions of the DFC are available: DFC CORE, DFC CORE+ and DFC SEED. All models use TOPTICA proprietary CERO-technology to achieve an unprecedented low-noise performance.

The DFC CORE and its high performance version DFC CORE+ come with a digital oscilloscope for beat monitoring and a GPS disciplined RF reference included. They both provide 4 or optionally 8 phase-stable outputs at 1560 nm.

Several extension modules are available that can convert the DFC CORE / DFC CORE+ outputs to any wavelength between 420 nm and 2200 nm. The extension modules can be upgraded at any time after purchase of the DFC CORE and are interchangeable between outputs.

In addition, beam combiner (DFC BC) and beat detector (DFC MD) units are available to provide RF beats between the DFC comb lines and cw lasers. The RF output signal of the DFC MD can be counted to determine the frequency of the cw laser. It also enables phase or frequency stabilization of the cw laser to the DFC using e.g. TOPTICA’s locking modules mFALC or DigiLock. In the DFC CORE+ version, the RF output signal can also be used to stabilize the DFC to the cw laser which serves as optical reference.

Such a DFC system can be combined with any of TOPTICA’s tunable diode lasers to achieve a complete, frequency referenced laser system including wavelength meter and counter all from one source.
