The DFC CORE + is a robust, 19 inch compatible optical frequency comb based on Erbium fiber technology. It is the core system for applications like optical clocks, micro wave generation or phase-locking of cw-lasers and can be equipped with additional wavelength extensions and options. Its unique fCEO-stabilization is based on Difference Frequency Generation (DFG) and comes with many advantages such as high robustness and ultra-low phase noise. The DFC CORE + features an outstanding stability and accuracy which is suitable for use with the best optical clocks. More than 20 years of engineering experience building high-quality scientific and industry-grade lasers went into its design, it’s a true TOPTICA laser.
