basic information
DFC CORE + is a robust, 19-inch rack-compatible optical frequency comb based on erbium fiber technology. It serves as a core system for applications such as optical lattice clocks, microwave generation, and phase locking of CW lasers, with the capability to supply additional wavelength extension options and other features. Its unique fCEO-stabilization is based on difference frequency generation (DFG), resulting in many advantages such as high robustness and ultra-low phase noise. DFC CORE + features outstanding stability and precision, making it ideal for high-precision optical lattice clocks. With over 20 years of technical experience in producing high-quality scientific and industrial-grade lasers, this design represents the true Toptica laser.
